... A baseball (m=0.14kg) has an initial velocity of v0=-38m/s as it approaches a bat. We have chosen the direction of approach as the negative direction. The bat applies an average force F that is much larger than the weight of the ball, and the ball departs from the bat with a final velocity of vf=+58 ...
