Impulse: A very light ping-pong ball moving east at a speed of 4 m/s collides with a very heavy stationary bowling ball. The Ping-Pong ball bounces back to the west, and the bowling ball moves very slowly to the east. Which object experiences the greater magnitude impulse during the collision?
A. Neither; both experienced the same magnitude impulse.
B. the Ping-Pong ball
C. the bowling ball
D. It is impossible to tell since the actual mass values are not given.
E. It is impossible to tell since the velocities after the collision are unknown.
