A sky diver jumps from a helicopter and is falling straight down at 30 m/s when his parachute opens. From then on, his downward acceleration is approximately
a = g - cv2 , where g = 9.81 m/s2 and c is a constant. After an initial "transient" period, he descends at a nearly constant velocity of 5 m/s.
a. What is the value of c, and what are its SI units?
b. What maximum deceleration is the sky diver subjected to?
c. What is his downward velocity whe he has fallen 2m from the point at which his parachute opens?
