Part B: Short Problems l8, 2 marks each] 'I. (K) A boy does 465 J of work pulling an empty wagon along level ground with a force of 111 N [31 below the horizontal]. A frictional force of 155 N opposes the motion and is actually slowing the wagon down from an initial high velocity. The distance the wagon travels is: Part C: Problems [5 marks each] Remember: Use Energy and Momentum Principles to solve the problems. 1. A 0.057 kg tennis ball is traveling at 32 mfs towards a player. The player hits the ball directly backwards at 36 mls. The ball is in contact with the tennis raquet for 0.00535 3. a. What is the impulse felt by the ball? b. How much force does the player exert on the ball? 0. Since there is limit to how much force a player can exert, briefly explain how a player can use proper technique to return a ball faster
