How can we identify what the horizontal force is when looking at a merry go round? The original question is... A child is on a merry go round sitting 1.2M from the center. She is traveling at 1.1m/s^2. What is the net horizontal force exerted on her and what is her centripetal acceleration?
A
35 kilogram child on a 12 meter diameter merry go round is moving
at 3.77 m/s. What is their centripetal acceleration and force?
Hint: the radius is half the diameter.
