A.)A 38.0 kg child is riding a playground merry-go-round that is rotating at 55.0 rev/min. What centripetal force (in N) is exerted if he is 1.25 m from its center? (Enter the magnitude.) B.)What centripetal force (in N) is exerted if the merry-go-round rotates at 4.5 rev/min and he is 8.00 m from its center? (Enter the magnitude.) C.) Compare each force with his weight. (Enter the ratios of the magnitudes.) F(a) w = F(b)
