block A (mass 2.28 kg) rests on a tabletop. It is connected by a horizontal cord passing over a light, frictionless pulley to a hanging block B (mass 2.57 kg ). The coefficient of kinetic friction between block A and the tabletop is 0.475. 2 questions: After the blocks are released from rest, find the speed of each block after moving 2.10 cm? After the blocks are released from rest, find the tension in the cord?
