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

A light string can support a stationary hanging load of 25.0kg before breaking. A 3.00kg

object attached to the string rotates on a horizontal table in a circle of radius .800m, and

the other end of the string is held fixed. What range of speed can the object have before

the string breaks?

2. Relevant equations

I have drawn a diagram and put these forces together.

3. The attempt at a solution

Sum of Forces in X=n and -mg

Sum of forces in Y= T and C sin theata

I know that the X canels out Fx = N-mg = 0

I get Y forces to be T + C sin theata = v^2/r

Am I starting this correct. Something doesn't seem right here.

Thanks,

Kevin
