Todd and susan are riding on a merry-go-round. todd rides on a horse toward the outside of the circular platform, and susan rides on a horse toward the center of the circular platform. when the merry-go-round is rotating at a constant angular speed, todd’s angular speed is:
a. exactly half as much as susan’s.
b. larger than susan’s. smaller than susan’s.
c. the same as susan’s.
d. exactly twice as much as susan’s.

Option (c)

Explanation:

The angular speed is defined as the rate of change of angular displacement.

Angular speed = angular displacement / time

Its unit is radian per second.

As the angular displacement in the position of both Todd and Susan is same in the same time so the angular speed of both Todd ans Susan is same.

Thus, option (c) is correct.
