A man who could only find a 75-kg blue rock nearby decides to drive a metal beach umbrella pole down into the soft sand of Galveston beach by dropping it straight down from a resting height of 2.3 meters. If the blue rock does not rebound off the pole just after contact (that means bouncing back and possibly hitting him in the head) then calculate the impulse the rock places on the umbrella pole. Assume the metal beach umbrella has a total mass of 175-kg

Consider an automobile accident in which a 1000 kg car strikes a tree in an inelastic collision. The speed of the car just before the collision was 72 km/hr. The duration of the impulse is 0.01s. What force does the passenger experience? In the same automobile, a passenger of mass 50 kg is sitting, unrestrained, in the front seat. The speed of the passenger was 72 km/hr before the collision and zero afterewards. The duration of the impulse that changes is or her momentum is again 0.01 s. What force does the passenger experience? Same automobile accident, except that the passenger is restrained by a seat belt and an air bag explodes at the moment of impact. The passenger's speed still changes from 72 km/hr to zero, but the air bag slows the time during which this change occurs to 0.01 s. What force does the passenger experience?
