Jane, whose mass is 50.0 kg, needs to swing across a river
(having width D) filled with person-eating croco- diles to save
Tarzan from danger. She must swing into a wind exerting constant
horizontal force SF, on a vine having length L and initially making
an angle u with the vertical (Fig. P8.81). Take D 5 50.0 m, F 5 110
N, L 5 40.0 m, and u 5 50.08. (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.
