A 55.0 kg high school baseball pitcher is holding a 149 g baseball as he slides horizontally on a frictionless surface with a velocity of +2.15 m/s, relative to the surface. He then throws the baseball with a velocity of +46.7 m/s relative to the surface. What is the player’s velocity after he releases the baseball?

  1. initialmomentum=0
    final momentum=initial momentum=0
    massman*velocityman+massball*velocityball=0

    solve for velocityman

  2. so do you plug the value in for the velocity of the man or no. either way this is too big of a number. The answer is 2.01 but I can't get that?
