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 with the vertical (Fig. P7.81). Take D = 50.0 m, F = 110 N, L = 40.0 m, and = 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.
A lump of putty (0.20 kg) hits a block (1.00 kg) at the bottom of a rough vertical loop that is 1.0 m in radius. After the collision, the putty/block combination slides through the loop. At the top of the loop, the combination has an apparent weight of 5.88 N. The coefficients of kinetic & static friction between the block and loop are 0.23 & 0.37 respectively and the work due to friction during the combination’s ascent is -17.34 J. Determine the speed of the putty/block combination at the top of the loop. Determine the speed of the combination at the bottom of the loop. Assuming that friction is much less than impact force, what was the speed the putty before the collision?
