Golf Ball and Ping Pong Ball

  1. Oct 22, 2009 #1
    If a golf ball and a Ping-Pong ball both move with the same kinetic energy, can you say which has the greater speed? Explain in terms of the definition of kinetic energy.

    Can you guys tell me if I'm thinking along the correct lines in my response...

    Kinetic energy = 1/2 M*V^2.
    Since the golf ball has a higher mass than the pingpong ball, the only way they could both have the same kinetic energy is if the golf ball has a slower speed.
