Achild sits on a fiberglass muskrat fastened 7.2 meters from the center of a merry-go-round platform that is rotating once every 15 seconds. what is the child's speed while sitting on the muskrat?

Child's speed, v = 3.01 m/s

Explanation:

It is given that,

Radius of the merry- go- round, r = 7.2 m

Time of rotation, t = 15 seconds

Let v is the child's speed while sitting on the muskrat. The displacement of the child is,

The speed of the child is given by :

v = 3.01 m/s

So, the speed of child while sitting on the muskrat is 3.01 m/s. Hence, this is the required solution.

the force on the thing and the distance the force moves the thing
