Tarzan tries to cross a river by swinging from one bank to the other on a vine that is 12.0 m long. His speed at the bottom of the swing is 8.3 m/s. Tarzan does not know that the vine has a breaking strength of 1.0 ✕ 103 N. What is the largest mass that Tarzan can have and still make it safely across the river?

f = m v^2 / r ... 1.0E3 > m * 8.3^2 / 12.0
