8. The head of a golf club with a mass of 0.25 kg is moving with a speed of 55 ms¹ just beforestriking a stationary 50g golf ball. After the collision, the golf club continues to move (in thesame direction) but with a reduced speed of 40 ms 1. Use conservation of momentum to findthe speed of the golf ball and determine whether or not the collision was elastic. Find theimpulse and force acting on the club during impact if the club and the ball are in contact for0.01 s

The main purpose of an air bag is to stop a passenger during a car accident in a greater amount of time than if the air bag were not present. For example, consider a 51 kg person traveling at 28 m/s (about 63 mph). Use impulse and momentum to calculate how many newtons of force would be required to stop the person in 0.035 s, 0.070 s, and 0.35 s. Note how the force changes with increased time. (Enter the magnitudes.) (a) How much force is needed to stop the person in 0.035 seconds? (b) How much force is needed to stop the person in 0.070 seconds? (c) How much force is needed to stop the person in 0.35 seconds?
