Ablock of mass 2.40 kg is on a tabletop and is connected to a second block by a pulley. the second block has a mass of 1.80 kg and hangs straight down. when the blocks are released from rest they move through a distance of 0.500 m, at which point the hanging block hits the floor. given that the coefficient of kinetic friction between the first mass and the horizontal tabletop is 0.450, find the speed of the blocks just before the second block lands. (use energy relations to solve.)
