Homework Help: Physics

Posted by Ted on Monday, March 25, 2013 at 11:31pm.

A stopper tied to the end of a string is swung in a horizontal circle. If a mass of the stopper is 13.0 g, and the string is 93.0 cm, and the stopper revolves at a constant speed 10 times in 11.8 secs, what is the tension on the string?

I tried solving this question using the formula T=mv^2/r. To use this i have to find the v. To find the v, i want to use v=2pi R/t. t in this formula is period. I'm confused on how to find t. Pls help
