Question: Just before a baseball is hit by a bat, it has a velocity of 30 m/s, 15 º below the pos x-axis. After it is hit by the bat, it has a velocity of 60 m/s, 30 º above the negative x-axis.
Part A: If the bat is in contact with the ball for 4 ms, what is the magnitude of the average acceleration of the ball while in contact with the bat?
I want you to clarify the physics in this above question.
