    1. The problem statement, all variables and given/known data

    The force exerted on a 0.145 kg baseball by a bat changes from 0.0n to 1.0x10^4 N over 0.0010 s, then drops back to zero in the same amount of time. THe baseball was going toward the bat at 25 m/s.

    a. Draw a graph of force versus time. What is the average force exerted on the ball by the bat?
    b. what is the acceleration of the ball?
    what is the final velocity of the ball, assuming that it reverses direction?

    2. Relevant equations newtons laws of motion

    3. The attempt at a solution
