the same distance. How does their momentum and kinetic energy compare?
14. A 2.0 kg ball moving east at 11 m/s collides elastically with a 1.5 kg ball moving 15 m/s west.
What is each of their speeds after the collision?
15. A baseball with a mass of 145 grams is moving horizontally at a speed of 35 m/s when it strike a
bat which causes it to move straight up vertically with a speed of 45 m/s. If the club was in contact
with the ball for 1.0 ms, what was the impulse provided to the ball by the bat, and what was the
average force of the bat on the ball?
