Question
Please help! I've tried many methods to this question and am running out of attepts.
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 , on a vine having length L and initially making an angle ? with the vertical (see below figure). Take D = 47.0 m, = 110 N, L = 40.0 m, and ? = 53.0 degree. With what minimum speed must Jane begin her swing to just make it to the other side? (If Jane can make it across with zero initial velocity, enter 0.) Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m/s Once the rescue is complete, Tarzan and Jane must swing back across the river. With what minimum speed must they begin their swing? Assume that Tarzan has a mass of 80.0 kg.
Explanation / Answer
Given m=50.0kg, D=50.0m, F=115N, L=40.0m, ?1=45.0
