A baseball of mass m = 0.14 kg is
thrown towards home plate at 100 mph.
The batter whacks it squarely and sends it
back towards center field at
a speed of 150 mph.
What is the ball's initial momentum?
What is the ball's final momentum?
What is the impulse, defined as the
change in momentum
impulse = (final momentum) - (initial momentum)
If the ball is in contact with the bat for
about t = 0.0007 s,
then what is the average force on the ball during that time?
