Tarzan, who weighs 634 N, swings from a cliff at the end of a convenient vine that is 13 m long . From the top of the cliff to the bottom of the swing, he descends by 1.4 m. The vine will break if the force on it exceeds 1220 N. What would the greatest force on the vine be during the swing? What is the proper stategy for solving this. Such as, "do i need to find a force first or a velocity or an angle" etc. I am not sure how to go about doing this .
