An amusement park ride consists of a rotating circular platform 8.00 meter in diameter from which 11.0 kilogram seats are suspended at the end of 2.50 meter mass less chains. When the system rotates, the chains make an angle θ =26.0 degree with the vertical.
(a) Determine the speed of each seat?
(b) Draw a free-body diagram of a 40.0 kg child riding in a seat. Determine the tension in each chain?
