Complete Question:
Andy and Charlie are riding on a merry-go-round. Andy rides on a horse at the outer rim of the circular platform, twice as far from the center of the circular platform as Charlie, who rides on an inner horse. When the merry-go-round is rotating at a constant angular speed, which of the following best describes Andy's angular speed?'
( ) twice Charlie’s
( ) impossible to determine.
( ) the same as Charlie’s
( ) half of Charlie’s
Answer:
The same as Charlie's
Explanation:
As a merry-go-round is a rigid body, all points in the rotating body must have the same angular velocity, i.e., thet must rotate the same angle in the same time.
Otherwise, the distance between any pair of points on a given radius could be different in different times, which is not possible in a rigid body,
Andy's angular speed is best described as being the same as Charlie's.
This is can be defined as how fast an object rotates or revolves relative to another point.
Since a merry-go-round is a rigid body in which all points in the rotating body must have the same angular speed. This means that they must rotate the same angle in the same time which was why it will be the same.
