1. The problem statement, all variables and given/known data A ball of mass m is suspended from a rope of length R. The ball is set into freely swinging circular motion a vertical plane. The centripetal acceleration of the ball at the top of the circle is 13g. What is the centripetal acceleration of the ball at the bottom of the circle. 2. Relevant equations 3. The attempt at a solution At the top, T + mg = mv^2/R At the bottom, T - mg = mv^2/R My question is does Ttop and Tbtm the same? Hint for this question?
