Homework Statement
When an object is moving in a vertical circle attached to a string, it can withhold a maximum tension at the bottom of it's path. Derive an expression for the maximum velocity the object can sustain without the string breaking. No data is given, and everything should be variables.
Homework Equations
V minimum equals the square root of gravity x radius
Fnet equals Fg - Tension at the bottom of a vertical path
Fnet equals mass x centripetal acceleration
The Attempt at a Solution
I attempted to use Fnet equals mass x centripetal acceleration - mg but that didn't work. I solved for v min in the previous problem, and found that it was the square root of gravity x radius, but I'm not sure how to go from that to v maximum.
