Tarzan plans to cross a gorge by swinging in an arc from a hanging vine (see Fig). If his arms are capable of exerting a force of 1200 N on the rope, what is the maximum speed he can tolerate at the lowest point of his swing? His mass is 72 kg and the vine is 4.8 m long

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, on a vine having length L and initially making an angle B with the vertical (Fig. P8.81). Take D= 50.0 m, F= 110 N, L= 90.0 m, and 8 = 50.0°.

(a) With what minimum speed must Jane begin her swing to just make it to the other side?

(b) Once the rescue is complete, Tarzan and Jane must swing back across the river. With what minimum speed must they begin their swing? Assume Tarzan has a mass of 80.0 kg. 

Jane, whose mass is 50 kg needs to swing across a river havingwidth D, filled with crocodiles to save Tarzan. She must swing intoa wind exerting constant horizontal force F on a vine having lengthL and initially making an angle θ with the vertical. Take D= 50 mF= 110 N L= 40 m and θ= 50 degrees.

a.) With what minimum speed nust Jane begin her swing to justmake it to the other side?

b.) Once the rescue is complete, Tarzan and Jane must swing backtogether across the river . With what minimum speed must they begintheir swing? Assuming Tarzan has a mass of 80 kg.
