(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A horizontal force of 210N is exerted on a 2.0kg object as it rotates uniformly on a horizontal plane with a radius of 0.9m. Calculate the speed of the object.

2. Relevant equations

I THINK the relevant equations for this problem are v=2[tex]\Pi[/tex]r/T and ar=v^2/r.

3. The attempt at a solution

v=2[tex]\pi[/tex]0.9/???

ar=???/0.9

My biggest problem is that for the life of me, I can't figure out how to find either the T or the v. If I knew how to do that, I could figure out the problem. I've also drawn a diagram of the problem.
