block A (mass 2.04kg) rests on a tabletop. It is connected by a horizontal cord passing over a light, frictionless pulley to a hanging block B (mass 3.00kg ). The coefficient of kinetic friction between block A and the tabletop is 0.215.
After the blocks are released from rest, find the speed of each block after moving 4.00cm .
