## Does This Illustration Show a Skydiver at Terminal Velocity?
Introduction
Terminal velocity is the maximum speed that a skydiver can achieve during freefall. It is reached when the force of gravity acting on the skydiver is equal to the force of air resistance acting on the skydiver. This force of air resistance is also known as drag.
How to Determine if a Skydiver is at Terminal Velocity
There are a few key factors that can help you determine if a skydiver is at terminal velocity. These factors include:
Body position: A skydiver at terminal velocity will be in a stable body position. They will not be tumbling or spinning.
Speed: A skydiver at terminal velocity will be traveling at a constant speed. They will not be accelerating or decelerating.
Altitude: A skydiver at terminal velocity will be at a constant altitude. They will not be climbing or descending.
Illustration Analysis
The illustration provided shows a skydiver in freefall. The skydiver is in a stable body position and is not tumbling or spinning. The skydiver is also traveling at a constant speed and is not accelerating or decelerating. The skydiver is also at a constant altitude and is not climbing or descending.
Conclusion
Based on the factors mentioned above, it is likely that the skydiver in the illustration is at terminal velocity.
Additional Information
The terminal velocity of a skydiver depends on a number of factors, including the skydiver’s weight, height, and body position.
The average terminal velocity of a skydiver is about 120 miles per hour.
Skydivers can reach terminal velocity in as little as 10 seconds.
Skydivers typically deploy their parachutes at about 5,000 feet above the ground.
