A movie stuntman (mass 91.4 kg) stands on a window ledge 6.88 m above the floor. Grabbing a rope attached to a chandelier, he swings down to grapple by the movie’s villain (mass 66.9kg), who is standing directly under the chandelier. (Suppose that the stuntman’s center of mass moves downward 6.88 m. He releases the rope just as he reaches the villain) If the coefficient of kinetic friction of their bodies by the floor is uk = 0.24, how far do they slide?
