Two boys of the same mass, 45 kg, are on a playground merry-go-round that has a diameter of 4.0 meters. Both boys are at the very edge of the ride. One boy stands with the coefficient of friction between his shoes and eh ride being .45 whereas the other is on his knees with a coefficient of friction of .3. Who will fly off first? At what speed will each boy fly off?
