A superhero (mass 80.0 kg) is on the edge of a window, holding a rope tied to a candlestick. To attack the villain (70kg mass) standing just below the lampstand, he lets himself swing with the rope from the window. Assuming that the superhero's center of mass drops H = 6.4 m during the ride and that the superhero releases the rope just when it hits the villain. If the average kinetic friction coefficient of their bodies with the floor...
