On a cold winter day, a penny (mass 2.50 g) and a nickel (mass 5.00 g) are lying on the smooth (frictionless) surface of a frozen lake. With your finger, you flick the penny toward the nickel with a speed of 2.30 m/s. Part A The coins collide elastically; calculate the magnitude of the velocity for each coin. Express your answers in meters per second separated by a comma. Part B What are the directions of their final velocities? Select all that apply. Select all that apply. The penny is moving away from you. The penny is moving back toward you. The nickle is moving away from you. The nickle is moving back toward you.
