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 magnitude of the force exerted by the first player's racquet on the ball with the magnitude of the force exerted by the second player's hand on the ball. FballOnRaqcuet/FballOnHand = ? 2. Relevant equations Aren't these two values just equal? Does it not take the same amount of force to (from the hand) to stop the ball ? 3. The attempt at a solution I said it was either 1 or -1 since the direction of the ball changed. Both of these are obviously wrong but I guess I don't really understand the question?
