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 velocity, co, in radians/second? Answer (4 points): 6 = 15. What is the tangential velocity, w,, of the girl? Answer (4 points): v,= 16. What is the total centripetal force, Fco she needs to exert to not fly off of the merry-go-round? Answer (4 points): F. = Points on page: 16 Subtotal: 96 17. Given the frictional force and her grip strength, is the girl able to stay on the spinning merry-go-round? Answer (4 points):
