1. The problem statement, all variables and given/known data a 0.144kg baseball is pitched horizontally at +38m/s. after it is hit by a bat, the baseball moves horizontally at -38m/s. a) what impulse did the bat deliver to the ball b) if the bat and the ball were in contact for 8.0*10^-4 seconds, what was the average force that the bat exerted on the ball? c) find the average acceleration of the ball during its contact with the bat. 2. Relevant equations J = Ft Ft = mv1 - mv2 3. The attempt at a solution a) Ft = mv Ft = 0.144 * -38 Ft = -5.472 kg m/s (they got -11 kg m/s) b) F(.0008) = 5.472 F = 5.472/.0008 F = 6840 N (they got 14000 N) c) F = ma 6840 = 0.144a a = 6840/0.144 a = 47500m/s^2 (they got 97000m/s^2) i know i am doing something seriously wrong here but i have no idea what??
