1. The problem statement, all variables and given/known data A small ball with a mass of 3.0kg revolves uniformly in a circle on a frictionless horizontal surface. The ball is attached to a string of 1.40m to a pin set at center of circle. The object makes 2rev/sec. a)find the centripetal accel b)find the tension exerted on the string 2. Relevant equations ac=v^2/r Fc= ma=m(4pi^2r/T^2) T= .5 3. The attempt at a solution if its uniform wouldnt the Fc=FT(force of tension) T would =.5 because 2 rev/1 sec? I am not sure how to find centripetal accel because i do not know how to find the velocity unless i am missing something..
