Problem 23PE

(a) A 22.0 kg child is riding a playground merry-go-round that is rotating at 40.0 rev/min. What centripetal force must she exert to stay on if she is 1.25 m from its center?

(b) What centripetal force does she need to stay on an amusement park merry-go-round that rotates at 3.00 rev/min if she is 8.00 m from its center?

(c) Compare each force with her weight.

Step-by-Step Solution:

Step 1 of Step 4</p>

A)

We have to find the centripetal force of the rotating merry-go-round from its center. Given mass of a child m=25 kg, angular acceleration and r is the radius from the center of rotating merry-go-round r=1.25m

Step 2 of Step 4</p>

=483 N is the centripetal force of the rotating merry-go-round from its center

Step 3 of 4

Step 4 of 4
