A child Standing on a playground merry-go-round is moving with a velocity of 1.36 m/s. When she is 1.20 m from the center of the merry-go-round, there is a centripetal force of 38.53 N acting on her.
a) What is the child's centripetal acceleration?
b) What is the child's mass?
c) What physical force acting on the child actually generates this centripetal force?
