In an amusement park ride called The Roundup, passengers stand inside a 18 m diameter rotating ring. After the ring has acquired sufficient speed, it tilts into a vertical plane. Consider that a rider has a mass of 61 kg.

a. Suppose the ring rotates once every 6 s. How much force does the ring push on her at the top of the ride?

Ftop =   N

b. Suppose the ring rotates once every 4.5 s. How much force does the ring push on her at the bottom of the ride?

Fbot =  N

c. What is the longest rotation period of the wheel that will prevent the riders from falling off at the top?

T =   s
