Suppose you are standing on the center of a merry-go-roundthat is at rest. You are holding a spinning bicycle wheel over yourhead so that its rotation axis is pointing upward. The wheel isrotating counterclockwise when observed from above. For this problem, neglect any air resistance or frictionbetween the merry-go-round and its foundation. Q.Suppose you now grab the edge of thewheel with your hand, stopping it from spinning. What happens to themerry-go-round?a. It remainsat rest. b. It begins torotate counterclockwise (as observed from above).c. It begins torotate clockwise (as observed from above).
