Tarzan (mass m = 80.0 kg) crosses a river by swinging on a vine. The vine (negligible mass) is 10.0 m long. If Tarzan's speed at the bottom of his swing is 5.0 m/s and the acceleration of gravity is 10 m/s2, then the tension in the vine will be O a. 1300 N b. 1400 N O c. 1000 N d. none of these e. 784 N
