1. A ball with a mass of .2 kg travelling at a speed of 35 m/s is struck by a bat. If the duration of the impulse is .001 seconds and the speed of the ball afterwards is the same as before, what is the average force (to the nearest Newton) of the impact?
2 On the other hand, if the magnitude of the average force in problem 1 is 20000 N, what is the speed to the nearest m/s after collision?
3 A 14 kg clay ball travelling left to right at a speed of 10 m/s strikes and sticks to a 5 kg ball at rest. What is the total momentum, to the nearest single decimal place of the composite ball after collision?
4 In problem 3), to 2 decimal places, what is the fractional loss of Kinetic Energy?
