## Expert Answer

Assuming his initial velocity is zero

A)v = at

v = − 9.8 × 1.3 s

v = 12.74 m/s downwards

B) d = 1 2 a t

2d = -4.9 (1.3)

2d= -8.28 m

C)low point when velocity = 0

Vf = Vi + at

0 = -12.74 + 4t

t = 12.74 4

t= 3.185 s

D) distance after stretch

d = V 1 t + 1 2 a t

2 d = − 12.74 ( 3.185 ) + 1 2 ( 4 ) ( 3.185 )

2d = – 40.58 m +20.29m

d = -20.3 m

Total distance = distance free fall + distance after stretch

d = -8.28 – 20.3m

d = -28.6 m

A tow truck pulls a car that is stuck in the mud, with a force of 2500 N as in Fig P5.27 The tow cable is under tension and therefor pulls downward and to the left on the pin at its upper end. The light pin is held in equilibrium by forces exerted by the two bars A and B. Each bar is a strut that is, each is a bar whose weight is small compared to the forces it exerts, and which exerts forces only through hinge pins at its ends. Each strut exerts a force directed parallel to its length. Determine the force of tension or compression in each strut. Proceed as follows Make a guess as to which way (pushing or pulling ) each force acts on the top pin Draw a free-body diagram of the pin. Use the condition for equilibrium of the pin to translate the free-body diagram into equations. From the equations calculate the forces exerted by struts A and B. If you obtain a positive answer, you correctly guessed the direction of the force. A negative answer means the direction should be reversed, but the absolute value correction should be reversed, but the absolute value correctly gives the magnitude of the force. If a strut pulls of a pin, it is in tension. If it pushes, the strut is in compression. Identify whether each strut is in tension or in compression.

## Why Do Bungee Jumpers Bounce Back Up? (Answered!)

There’s more going on in today’s world than ever before, and more people are looking for exciting ways to distract them from their mundane life.

No matter the severity of the extreme sport or activity someone is hoping to do, it’s a compelling manner for anyone to accomplish.

Nowadays, people want to excite themselves to do something new, and what better way to do that than bungee jumping.

With bungee jumping in mind, why do bungee jumpers bounce back up?

**To answer this question…bungee jumpers bounce back because of the stretchy material involved with the bungee cord and gravity. The earth’s gravitational force allows the bungee jumper to bounce back up while the fall slows down and begins to reverse. It’s relatively straightforward how the process works, and gravity is the main reason they bounce back up instead of falling straight to their demise.**

Like anything else, there’s a lot of interest among people with something so extreme, like bungee jumping.

The mass populous typically doesn’t take a deep dive with something as intense as bungee jumping.

Still, there’s always interest in niche subjects that usually don’t fall under the safe or standard category.

People want to know the exciting lifestyle of a particular topic, and bungee jumping falls under that category.

Down below, we’re going to discuss everything there is to know about bungee jumping and bouncing back up.

Although this might sound like a niche question, there’s a lot involved in the matter that most people don’t realize.

We’ll discuss if bungee jumpers always bounce back up, if it’s dangerous, and the concerns.

From there, we’ll discuss a plethora of other information related to the subject.

Let’s get started!

**Do bungee jumpers always bounce back up?**

Whenever someone brings up the subject of bungee jumping, people tend to question the issue’s safety, since it seems like such an insane activity.

A person is quite literally jumping from a point straight down with a stretchy cord to save them from dying for starters.

When it’s explained like this, it sounds quite terrifying and challenging to comprehend why anyone would want to do this.

However, what many people fail to realize is the safety attached to bungee jumping is very good.

For starters, only 1 in 500,000 instances of bungee jumping result in an accident of some kind.

Considering the number of people that do bungee jumping, this is a significant number and demonstrates how safe it is.

Like other extreme sports, there are many precautions and check-ups on the bungee jumping, no matter where you go.

Although every bungee jumping place is different and offers a different experience, there’s typically an overhead ruling board that dictates what can and can’t happen.

On top of this, there’s a lot to know regarding bungee jumping.

Whether you discuss the budget involved in the matter, rules, or safety precautions, everybody has questions pertaining to bungee jumping.

Fortunately enough, not coming back up after you jump doesn’t happen very often and is quite rare.

**Is it dangerous for bungee jumpers to bounce?**

When you bring up the subject of jumping with the hopes that a stretchy cord will bounce you back up to safety, of course, there is some danger involved in the matter.

If you go back to when bungee jumping was first invented, obviously it isn’t how it is today.

Back in the day, bungee jumping incidents were more often, but it’s never been safer than it is today.

Regardless of this, people need to realize what they’re signing up for and what’s involved in making sure you’re as safe as you can be.

Still, you never know when a bungee jumping place might try to cut corners that can potentially hinder your fun.

With this in mind, always be aware of what is going on, and if you get any inclination that the workers involved aren’t taking it seriously, don’t run the risk.

If you roll the dice and run the odds, you never know what can go wrong, which should always be avoided with an example like this.

It’s always better to be safe than sorry, especially if you’re discussing something extreme like bungee jumping.

As fun and exciting it might be to begin your bungee jumping journey finally, you need to realize when something is a potential danger.

Never try to force a situation, since you never know when something can go wrong and potentially injure you.

**What are the concerns for bungee jumpers bouncing back up?**

There are concerns to note when you discuss the severity of bungee jumping and someone potentially getting injured from it.

Although every place is different, there are a few points to consider while you’re trying to bounce back up.

For starters, look at yourself and see if you’re comfortable enough to do bungee jumping correctly.

If not, you run the risk of having a panic attack while doing it, which should always be avoided since this can cause an issue.

Besides your personal use, you need to look at the people involved in the matter and see if they’re doing everything correctly.

If they try to rush you along and seem like they don’t care about your well-being, definitely consider another route.

Lastly, make sure you follow the rules. If they tell you a list of things you shouldn’t do, make sure you follow it closely.

Ignoring the rules and doing whatever you want is never a good idea since you never know what potential issue can present itself.

Another point to consider is what you eat before you go bungee jumping.

Obviously, if you eat quite a bit, you’ll have issues bouncing back up while bungee jumping.

Often, people forget about essential issues like that, and it’s a point to remember before beginning your bungee jumping journey.

**What happens if a bungee jumper doesn’t bounce back up?**

Technically speaking, a bungee jumper doesn’t bounce all the way back up for them to be safe.

The process is actually much more straightforward than that.

The jumper attached to the cord jumps down; they free-fall until it becomes tightened, prompting them to get to a standstill eventually.

Once they’re in a standstill, they’re eventually brought back up and taken off of the cord very safely.

With something as severe and potentially dangerous as bungee jumping, people need to make sure they’re as safe as possible in the process.

On the other hand, if a bungee jumper doesn’t come back up and the cord breaks, that’s never good.

Most of the time, if this were to happen, the bungee jumper is either seriously injured or worse.

Either scenario is never good to think about if you’re considering to begin bungee jumping.

Still, the likelihood of a severe injury or accident occurring from a bungee jumper is very unlikely.

There are enough technology and safety precautions available to make sure issues like this don’t happen in today’s world, and that’s a good thing.

Whatever the case might be, it’s essential to highlight the potential issues that can present themselves, since it’s never a fun part to think about what can happen.

As long as you follow the rules and know what can happen, you should be fine.

**Does weight affect bungee jumpers bounce?**

Generally speaking, the overall force of bungee jumping is affected by the person’s weight involved in the matter.

For instance, if someone weighs over 300 pounds, they’ll experience more force than someone who weighs 150 pounds.

As far as weight limit concerns, it’s important to note that more massive people do have a particular set of precautions to follow.

For starters, if you feel like your weight is of concern, it’s most likely in your best interest to try something bungee jumping.

This isn’t to shame you into not doing what you want to do, but realize there’s a lot of concern with safety precautions with weight.

You don’t want to harm yourself doing something that’s meant for fun, which is why you should be honest with yourself in the process.

Lastly, every company you plan on going with to bungee jump has different weight limits.

Remember to look at the weight limits and requirements listed so you know if you can do it or not.

It should be reasonably straightforward for you to check out, and once you do, you can try it out or not.

Plus, if you find you’re a touch too heavy or light to try it out, don’t be discouraged.

You can either try to find another option with a higher weight limit, or you can try to lose or gain weight for it.

There are a lot of options to consider, so make sure you note them.

Bungee jumping is an extreme activity for plenty of reasons, and it’ll continue to interest people as long as there are individuals who want to add something extreme to their life.

Be sure to check out local bungee jumping options near you and try it out!
