Spl. A fast ball thrown with a velocity of 40 m/s (approximately 90 MPH) is struck by a baseball bat, and a line drive comes
back toward the pitcher with a velocity of 60 m/s. The ball
is in contact with the bat for a time of just 0.04 s. The base-
ball has a mass of 120 g (0.120 kg).
a. What is the change in momentum of the baseball during
this process?
b. Is the change in momentum greater than the final
momentum? Explain.
re. What is the magnitude of the impulse required to pro-
duce this change in momentum?
d. What is the magnitude of the average force that acts on
the baseball to produce this impulse?
