Textbook Problem

Andrea and Chuck are riding on a merry-go-round. Andrea rides on a horse at the outer rim of the circular platform, twice as far from the center of the circular platform as Chuck, who rides on an inner horse. When the merry-go-round is rotating at a constant angular speed, Andrea’s angular speed is (a) twice Chuck’s (b) the same as Chuck’s (c) half of Chuck’s (d) impossible to determine.

To determine
How the angular speed of Andrea is related to that of Chunk.

Explanation

Given Info: Andrea is riding on a horse at the outer rim of the circular platform. The distance between the center of the circular platform to Andrea is twice the distance between the center and Chunk.

Explanation:

When a rigid body is rotating about any axis, all the points in the rigid body have the same angular speed.

Since Andrea and Chunk are in the same circular platform which can be treated as a rigid body, the angular speed of Andrea and Chunk are same...
