Two blocks are connected by a massless string that runs across a massless, frictionless pulley. The block with a mass of my = 7.01 kg hangs off the edge of a vertical drop. A second block with a mass of me = 13.9 kg sits on a surface that is inclined at an angle of 0 = 28.2' above the horizontal. Once the blocks are released, block 1 falls as block 2 slides down the surface. When both blocks are moving with a speed of 0.448 m/s, what is the y-component of the momentum of block 1?
