1. The problem statement, all variables and given/known data You swing a 6.5 kg bucket of water in a vertical circle of radius 1.2 m. (a) What speed must the bucket have if it is to complete the circle without spilling any water? m=6.5 r=1.2 2. Relevant equations maybe f=ma f=m(v^2/r) 3. The attempt at a solution What I did was set fc=6.5(V^2)/1.2, and since f=ma, I had a (or v/t)=V^2/1.2. I end up with the equation 1.2vt, which just brings me in circles. What can I do?
