1. The problem statement, all variables and given/known data A 1.5 kg ball is tied to a string that is .75 m long and whirled in a verticle circle. A) Find the tension in the string at the top of the circle B) Find the tension in the string at the bottom of the circle 2. Relevant equations Fc=mac ac= v2/r 3. The attempt at a solution A) Fnet= Ft + Fg Fnet = Ft + (1.5)(10) B) Fnet = Ft - Fg Fnet = Ft - (1.5)(10) As you can see, I did not get very far in my calculations as I am very confused where to go from here. Both equations would require velocity which is not given and I don't know how to find it.
