(a) during an ice skating performance, an initially motionless 80.0-kg clown throws a fake barbell away. the clown’s ice skates allow her to recoil frictionlessly. if the clown recoils with a velocity of 0.500 m/s and the barbell is thrown with a velocity of 10.0 m/s, what is the mass of the barbell? (b) how much kinetic energy is gained by this maneuver? (c) where does the kinetic energy come from?
