An amusement park ride consists of a rotating circular platform 8.00 m in diameter from which 10.0 kg seats (empty) are suspended at the end of 2.50 m massless chains. When the system rotates the chains make an angle of 0 = 28.0 with the vertical. (a) Find the tension ( F r) in the chain when a 40.0 kg child is riding in a seat [HINT: Horizontal Clrcle Draw the FBD of child and seat, & determine ZFy=m ay =0]
(b) A child occupies each seat. What is the speed of each seat? [HINT: Determine the radius of the horizontal circle traced out by each seat. Use ZFx = m ax ]
