1. The problem statement, all variables and given/known dataA 0.160 kg ball attached to a light cord is swung in a vertical circle of radius 70.0 cm. At the top of the swing, the speed of the ball is 3.26 m/s. The centre of the circle is 1.50 m above the floor. What is the velocity if the ball is 30 degrees below the horizontal 2. Relevant equations 3. The attempt at a solution Was going to use this equation,T=mv^2/r - mg Sin() but I dont have the tension, and I dont know how to find it at and angle. So there must be another way that Im not thinking of.
