Save a Skydiver

Question 1

In this exercise you will use the Java applet of the skydiver you used previously.

Use your left mouse button to draw the skydiver's velocity and acceleration in terms of distance in free-fall. After you have drawn the curve, compare your plots with the ones drawn in the applet.

Now press the start button on the applet and watch the skydiver fall and his/her parachute deploy.

Question 2

What is the terminal velocity of a skydiver with a parachute?
Assume kf = 28.8 Ns2/m2 for a parachute 24 feet in a diameter and m = 80 kg for the skydiver-parachute combination.

Question 3

How do increases in k and m affect the velocity and acceleration of the skydiver? The answer is a qualitative one for this question.

Question 4

Plot vf(y) and af(y) for the skydiver with a parachute. Assume m = 80 kg. Compare the plots with those for the skydiver without a parachute (Falling in a Fluid - Practice - Question 5).
