You are standing on the edge of a rotating merry-go-round. You feel an acceleration pointing towards the center of the merry-go-round. This means: a) The rate of rotation of the merry-go-round is increasing. b) The rate of rotation of the merry-go-round is decreasing. c) The rate of rotation of the merry-go-round is constant. d) We cannot say anything about the rate of rotation. e) The merry-go-round is not rotating, it is at rest. As you are leaving a building, the door opens outward. If the hinges on the door are on your right, what is the direction of the angular momentum of the door about its hinges as you open it? a) up b) down c) to your left d) to your right e) forwards
