A Ping-Pong ball moving East at a speed of 4 m/s collides with a 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) It's impossible to tell since the velocities after the collision are unknown.
  C) the bowling ball
  D) the Ping-Pong ball
