(adsbygoogle = window.adsbygoogle || []).push({}); "Tarzan" problem

1. The problem statement, all variables and given/known data

"Tarzan (m=85kg) tries to cross a river by swinging from a 10.0m long vine. His speed at the bottom of the swing, just as he clears the water, is 8.0 m/s. Tarzan doesn't know that the vine has a breaking strength of 1.0 x 10^3 N Does he make it safely across the river? Justify your answer."

2. Relevant equations

[tex]F_{c}=\frac{mv_{t}^2}{r}[/tex]

3. The attempt at a solution

I attempted to substitute in the variables as such:

[tex]F_{c}=\frac{85kg*\left(8.0\frac{m}{s}\right)^2}{10.0m}[/tex]

I got 544N, which is not the answer(1.37x10^3N is his 'weight' at this point, greater than the rope). Am I missing something obvious?
