Tarzan, with a mass of 80.0 kg, wants to swing across a ravine on a vine, but the cliff on the far side of the ravine is 0.900 m higher than the cliff where Tarzan is now, and 1.80 m higher than Tarzan?s lowest point in his swing. Use g = 9.80 m/s^2. If Tarzan swings along a circular arc of radius 12.0 m, what is the tension in the vine when Tarzan reaches the lowest point in his swing?
