An amusement park ride consists of a rotating circular platform 11.6 m


011

An amusement park ride consists of a rotating circular platform 11.6 m in diameter from which 10 kg seats are suspended at the end of 3.1 m massless chains. When the system rotates, the chains make an angle of 13.8° with the vertical. 

The acceleration of gravity is 9.8 m/s2
