Question

Two children are riding on a merry-go-round. Child A is at a greater distance from the axis of rotation than child B. Which child hasthe larger linear displacement?Select one:a. There is not enough information given to answer the question.b. Child Ac. They have the same non-zero linear displacementd. Child Be. They have the same zero linear displacement.

Answer 1

The linear displacement in a rotation is given by:

`s=r\theta`

where r is the distance from the axis of rotation and theta is the angular displacement.

Since the linear displacement is proportional to the radius we conclude that child A has a larger linear displacement.
