questions and show your work.
Jane, whose mass is 50.0 kg, needs to swing across a river (having width D) filled with person-eating crocodiles to save Tarzan from danger. She must swing into a wind exerting constant horizontal force F vector, on a vine having length L and initially making an angle theta with the vertical (see below figure). Take D = 48.0 m, F vector = 115 N, L = 40.0 m, and theta...
