After the cable snaps and the safety system fails, an elevator cab free-falls from a height of 31 m. during the collision at the bottom of the elevator shaft, a 90 kg passenger is stopped in 4.5 ms. (assume that neither the passenger nor the cab rebounds.) (a) what is the magnitude of the impulse on the passenger during the collision? n · s (b) what is the magnitude of the average force on the passenger during the collision? n suppose the passenger were to jump upward with a speed of 7.1 m/s relative to the cab floor just before the cab hits the bottom of the shaft. assume the same stopping time as above. (c) what is the magnitude of the impulse on the passenger during the collision? n · s (d) what is the magnitude of the average force on the passenger during the collision? n
