(14%) Problem 4: A merry-go-round at an amusement park consists of an outer ring of horses and an inner ring of elephants. The ring of eight horses has a radius of ) = 8.9 m. Each of the eight horses has a mass m = 105 kg. The ring of four elephants has a radius of re = 6.6 m and each of the four elephants has a mass me = 195 kg. The platform of the merry-go-round itself has a mass of mo = 1550 kg and a radius of ro = 10.1 m. At it's operating speed, the merry-go-round makes one revolution every t = 1/ s.
