## Homework Statement

Tarzan runs at 6 m/s and grabs a vertical vine (negligible mass) of length 4.1 m which is tied to a branch at the top. Tarzan then swings up.

Determine the maximum height Tarzan will swing up and the maximum angle the vine will make with respect to vertical.

## Homework Equations

mgh = 1/2mv

^{2}?

## The Attempt at a Solution

I did a problem about the height of the swing previously, but mass was given. I would solve for m if height was given, but neither are so I'm not sure where to begin. I'm sure there is another equation. Is this a pendulum problem? We haven't covered much on pendulums. Sorry if this is not enough for an attempt at a solution.
