A 15 year old girl is riding on a playground merry-go-round, being pushed around by her friend, similar to that pictured above. The rider has a mass of 50.0 kg and a two handed grip strength of 445 N. The coefficient of friction between her and the merry-go-round is 0.100. Her friend spins her at a rate of 40 rev/min. 13. What is the frictional force, f, acting on the girl? Answer (4 points): f= 14. What is the angular...

A 40.0-kg child running at 3.00 m/s suddenly jumps onto a stationary playground merry-go-round at a distance 1.50 m from the axis of rotation of the merry-go-round. The child is traveling tangential to the edge of the merry-go-round just before jumping on. The moment of inertia about its axis of rotation is 600 kg ? m2 and very little friction at its rotation axis. What is the angular speed of the merry-go-round just after the child has jumped onto it?...
