1. homework statement

after the cable snaps and the safety system fails, an elevator cab free falls from a height of 36m. during the collision at the bottom of the elevator shaft, a 90 kg passenger is stopped in 0.005 s. assume that neither the passenger nor the cab rebounds. what are the magnitudes of the:

a) impulse and b) average force on the passenger during the collision?

if the passenger were to jump upward with a speed of 7.0 m/s relative to the cab floor just before the cab his the bottom of the shaft, what are the magnitudes of the:

c) impulse and d) average force (assuming the same stopping time)?

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
