Question
You are looking down on a meny-go-round and observe that it is rotating clockwise. What is the direction of the merry-go-round's rotational velocity? If the merrygo-round is slowing down, what is the direction of its rotational acceleration?
Step 1
The merry-go-round is rotating in a clockwise direction. According to the right-hand rule, if you curl your fingers in the direction of rotation (clockwise in this case), your thumb will point in the direction of the rotational velocity. Therefore, the rotational Show more…

You are going around on a Merry-go-round. As the Merry-go round slows down before it stops what is true of the Tangential acceleration? Tangential acceleration is zero Tangential acceleration is in the direction of the Tangential velocity. Tangential acceleration is opposite the direction of the Tangential velocity. Tangential acceleration is toward the center of the Merry-go-round. Tangential acceleration is directed radially out from the center of the Merry-go-round
The blades of a blender on a counter are rotating clockwise as you look into it from the top. If the blender is put to a greater speed what direction is the angular acceleration of the blades?
