1. The problem statement, all variables and given/known data A) An amusement park ride consists of a rotating circular platform 10.8 m in diameter from which 10 kg seats are suspended at the end of 2.34 m massless chains. When the system rotates, the chains make an angle of 29.4◦ with the vertical. The acceleration of gravity is 9.8 m/s2 . What is the speed of each seat? Answer in units of m/s. B) If a child of mass 42.6 kg sits in a seat, what is the tension in the chain (for the same angle)? Answer in units of N. 2. Relevant equations ∑F=ma_(c)= m (v^2/r) 3. The attempt at a solution If this where talking about the string starting from origin of pole, wouldn't be that hard. But since they added the top diameter, I am not sure how to tackle this problem.
