Homework Statement

A 75 kg student runs at 5 m/s, grabs a rope, and swings out over a lake. He releases the rope when his velocity is zero. a) What is the angle when he releases the rope? b) What is the tension in the rope just before he releases it? c) What is the maximum tension in the rope?

Homework Equations

$$\Lambda$$KE = $$\frac{1}{2}$$mv$$_{f}$$$$^{2}$$ - $$\frac{1}{2}$$mv$$_{o}$$$$^{2}$$ = mgh

The Attempt at a Solution

(75/2)*25 = 75 * 9.8 * h
h = 1.276

this is all I got.
