A sky diver has a weight of 750 N. Suppose that the air resistive force acting on the diver increases in direct proportion to his velocity such that for every 10 m/s that the diver’s velocity increases, the force of air resistance increases by 100 N.
a. What is the net force acting on the sky diver when his velocity is 40 m/s?
b. What is the acceleration of the diver at this velocity?
c. What is the terminal velocity of the sky diver?
d. What would happen to the velocity of the sky diver if for some reason (perhaps a brief down draft) his velocity exceeded the terminal velocity? Explain.
