a photo of a swing ride at an amusement park. The structure consists of a horizontal, rotating, circular platform of diameter D from which seats of mass m are suspended at the end of massless chains of length d. When the system rotates at constant speed, the chains swing outward and make an angle ? with the vertical. Consider such a ride with the following parameters: D = 7.00 m, d = 2.50 m, m = 10.4 kg, and ? = 26.0°.
(a) What is the speed of each seat?
m/s
(b) Find the tension in the chain.
