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

2. Relevant equations

ƩF = ma

3. The attempt at a solution

I know how to break this problem up into the x and y direction

Y Direction:

Ft cosθ - Fg = 0

X Direction:

Ft sinθ - Fg = mv^{2}/ r

The hint says to find the inward radial component. I'm guessing this means to find r, because I think that is the only thing missing for me to solve this. To find r I think I would use some combination of the length of the string and theta, but don't exactly know.

Thanks for any help!
