1. The problem statement, all variables and given/known data During a tennis volley, a ball that arrives at a player at 40 m/s is struck by the racquet and returned at 40 m/s. The other player, realizing that the ball is out of bounds, catches it in her hand. Assuming the time interval of contact is the same in both cases, compare the force exerted by the first player's racquet on the ball with the force exerted by the second player's hand on the ball. 2. Relevant equations None given. The book did not provide me with one I could use. 3. The attempt at a solution I have submitted 0 as my answer because I felt that with both of them going the same speed, there would be 0 difference in force, but I got this problem incorrect (5 more attempts remaining at the time of this message). Mass is not given either, so how would one find the difference of force between these two using only velocity?
