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

Tarzan plans to cross a gorge by swinging in an arc from a hanging vine. If his arms are capable of exerting a force of 1.4x10^3 N on the vine, what is the maximum speed he can tolerate at the lowest point of his swing? His mass is 80kg and the vine is 4.8m long.

2. Relevant equations

F=ma

v=(2pi*r)F

3. The attempt at a solution

I used the second equation to find v and ended up with 42,202 m/s, which seems way too high. I'm doubting this was the right equation to use since I didn't insert mass, and I'm not sure if 4.8m is the radius.
