Block A with a mass of 2.25 kg rests on a tabletop. It is connected by a horizontal cord passing over a light, frictionless pulley to a hanging block B with a mass of 1.30 kg. The coefficient of kinetic friction between block A and the tabletop is 0.450. After the blocks are released from rest, determine the following: A B (a) free-body diagram of each block; (b) speed of each block after moving 3.00 cm? (Ans: 21.8 cm/s) (c) tension in the cord (Ans: 11.7 N)
