Tarzan, who has a mass of 85.0kg, is going to cross a gorge by swinging in an arc from a 4.0m long hanging vine. If his arms are capable of exerting a force of 1500N on the rope, what is the maximum speed he can tolerate at the tolerate at the lowest point of his swing?

Remember that he has to support his own weight in addition to the centripetal force at the lowest point:
mv²/r + mg = 1500N
Solve for v.
