detailed solution

1. A 45.9 g golf is initially at rest on the tee. As the club hits the ball, the ball acquires a speed of 76.0m/s. What is the change in momentum of the golf ball? 2. A ball has a speed of 12.45 m/s with a mass of 23kg. What momentum would the bullet have if: a. twice the mas and was moving with the same speed. b. half the mass and was moving with three times the speed. 3. What force is needed to stop a 500Kg bicycle in 6.0 s if it is traveling at 45m/'s
