1. The problem statement, all variables and given/known data Tarzan, who weighs 619 N, swings from a cliff at the end of a convenient vine that is 14 m long (Fig. 8-37). From the top of the cliff to the bottom of the swing, he descends by 4.3 m. The vine will break if the force on it exceeds 1550 N. What would the greatest force on the vine be during the swing? **image attached** 2. Relevant equations Fynet=T-mgcos(theta)=(mv^2)/r T=mgcos(theta)+(mv^2)/r 0+mgh=(1/2)mv^2+0 (initial and final energies) v^2=2gh 3. The attempt at a solution I attempted this problem and plugged everything into the tension equation, but I don't know how to get the angle for the cosine, I put in zero and my tension was 424.44 N and that's obviously not right. Can anyone help me out?
