I've been messing around with this problem for a while now and am getting absolutely nowhere. I was wondering if anyone could help me work it out... --A movie stuntman (mass 80.0 kg) stands on a window ledge 5.0 m above the floor. Grabbing a rope attached to a chandelier, he swings down to grapple with the movie's villain (mass 70.0 kg), who is standing directly under the chandelier. (Assume that the stuntman's center of mass moves downward 5.0 m. He releases the rope just as he reaches the villain.) A: With what speed do the entwined foes start to slide across the floor? Take the free fall acceleration to be 9.8 B: If the coefficient of kinetic friction of their bodies with the floor is mu_k= 0.215, how far do they slide? I don't recall doing anything at all like this in class and can't find any examples like this so I'm really at a loss as to how to approach it.
