Andrew was running late for class and could only find a parking space next to the golf course. His new truck was hit by a 0.300 kg golf ball which left a 0.400 cm dent in the hood. The golf ball was falling with a velocity of 8.00 m/s. a) What is the initial momentum of the golf ball? b) what average force did the hood of the truck exert on the ball to stop it? c) how long did it take for the hood to stop the ball?
