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 1400 N on the rope, what is the maximum speed he can tolerate at the lowest point of his swing? His mass is 80 kg and the vine is 4.8 m long? 2. Relevant equations net force = ma 3. The attempt at a solution I'm not sure how to deal with the force of tension in this problem net force radial direction = m a radial direction = Fr = Ft + Farm - Fg sense I don't know what the force of tension is in this problem I got down to this v = ((.06 kg^-1 m)Ft - 37 s^-2 m^2)^(2^-1) is the force of tension equal to what?
