A movie stuntman (mass 80.0kg) stands on a window ledge 5.0 m above the floor. Grabbing a rope attached to a chandelier, heswings down to grapple with the movie's villian (mass 70.0 kg), whois standing directly under the chandelier.(assume that thestuntman's center of mass moves downward 5.0 m. He releasesthe rope just as he reaches the villian). a) with what speed do the entwined foes start to slide across the floor?

a) with what speed do the entwined foes start to slide across the floor?
We are given mass of stuntman. We are also given its initial height. We are given mass of villian. The villian is initially at rest. The potential energy of stuntman at top is converted to kinetic energy at bottom. We first find initial velocity of stuntman. We then use conservation of momentum to find speed of both persons after they are entwined.
