During an ice skating performance, an initially motionless 75-kg clown throws a fake barbell away horizontally. The clown’s ice skates allow her to recoil frictionlessly. a) If the clown recoils with a speed of 0.475 m/s and the barbell is thrown with a speed of 11.5 m/s, what is the mass, in kilograms, of the barbell?  b)How much kinetic energy, in joules, is gained by this maneuver?
