1. The problem statement, all variables and given/known data A 0.145 kg baseball pitched horizontally at 39.0 m/s strikes a bat and is popped straight up to a height of 37.0 m. (a)If the contact time between bat and ball is 1.0 ms, calculate the magnitude of the average force between the ball and bat during contact. (b)Find the direction of the average force on the ball. 2. Relevant equations p=mv F=p/t 3. The attempt at a solution This seemed like a really simple problem to me, but Mastering Physics said my answer was wrong. I tried to find momentum using p=mv, p= 0.145 kg(39.0 m/s) = 5.655 Then I plugged this into F=p/t and got F=5.655/0.001 s =5655N, which it said was wrong. Am I missing something? What do I do with the height? Also I don't know what to do with part b at all.
