Question

A coin C of mass 0.050 kg is placed on a horizontal disk at a distance of 0.20 m from the center, as shown above. The disk rotates at a constant rate in the clockwise direction as seen from above. The coin does not slip, and the time it takes for the coin to make a complete revolution is 1.2 s.

  1. If the experiment in part (c) were repeated with a second, identical coin glued to the top of the first coin, how would this affect the answer to part (c) ? Explain your reasoning.
