A pitched 140 g baseball, in horizontal flight with a speed U

A pitched 140 g baseball, in horizontal flight with a speed U of 39 m/s, is struck by a batter. After leaving the bat, the ball travels in the opposite direction with speed Uf, also 39 m/s. a) What impulse J acts on the ball while it is in contact with the bat? b) The impact time At for the baseball-bat collision is 1.2 ms. What average force acts on the baseball? c) What is the average acceleration a of the baseball?
