Question

그래서 오르비의 고수님들께 한번 여쭤보고 싶네요.^^ 도대체 답이 뭔가요?ㅠㅠ

A movie stuntman (mass 80.0 kg) stands on a window ledge 5.0 m above the floor (Fig. 8-40). 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 the stuntman’s center of mass moves down 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? b) If the coefficient of kinetic friction of their bodies with the floor is μ = 0.250, how far do they slide?
