1. The problem statement, all variables and given/known data A 1.11 kg disc is whirled in a vertical circle with radius 0.680m about a fixed point. Find the tension at the top if the speed at the top is 8.76 m/s. 2. Relevant equations F= ma F= m* Acp Acp= m(w^2*r) 3. The attempt at a solution I figured centripetal force was acting on the mass so I used the equation w=v/r to find omega(w), then I found the Acp. But that answer is incorrect. If at the top of a circle will the tension be the same Acp.
