A 0.21-kg baseball has an initial velocity of 41 m/s as it approaches a bat. We have chosen the direction of approach as the positive direction. The bat applies an average force that is much larger than the weight of the ball, and the ball departs from the bat with a final velocity of -61 m/s. Assuming that the time of contact is 1.1 milliseconds, find the average force exerted on the ball by the bat.
