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

If a ball is being swung in a vertical circle at the end of a light cord at a constant speed of 3.35m/s when the the radius of the vertical circle is 0.70m and the mass of the ball is 0.160kg calculate the tension in the cord at the top of the swing.

2. Relevant equations

fc=T+fg

3. The attempt at a solution

m=0.160kg v=3.26m/s r=0.7m

T=fc-fg fc=T+fg T= ( mv2/r) - mg

now what confuses me is that this equation is used for tension in the cord at the bottom of the circle and it gives me the same answer what can i do to get a differant answer for tension in the cord at the top of the cord
