## Homework Statement

You swing a 1.60m long string with a metal ball attached to its end in a vertical circle, such that the speed of the ball does not change but the rope is always taut. The tension in the string when the ball is at the bottom of the circle is 60.0N more than the tension when the ball is at the top. Find the mass of the ball.

## Homework Equations

Fc=mv^2/r

ac=v^2/r

Equations that have to do with vertical circle

## The Attempt at a Solution

I do not understand vertical circles but I tried doing the Tbottom=Ttop+6mg

I am unsure of the answer but I did 60+Ttop=Ttop+6mg

60=6mg

10=mg

m=1.02 kg

but I think its wrong
