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

Tarzan swings from a vine 20 m long which makes an angle of 30° with the vertical. If he pushes off with a speed of 2 m/s, what is the tension in the vine at the lowest point of the swing? Tarzan has a mass of 80 kg.

2. Relevant equations

centripetal accelaration force = F

m = mass

r = radius of circle

v = tangential speed

F=m(v^2)/r

1/2mv^2 + mgh = 1/2mv^2 (I'm not sure about this, though)

3. The attempt at a solution

F = 80 (2^2)/ 20

F = 16 N

I don't know how to integrate the angle measure into the problem.
