CP? As shown in Fig. E5.34, block A (mass 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 (mass 1.30 kg). The coefficient of kinetic friction between block A and the tabletop is 0.450. The blocks are released then from rest. Draw one or more free-body diagrams to find (a) the speed of each block after they move 3.00 cm and (b) the tension in the cord.
Solution 37E Step 1: Mass of block A (m ) a 2.25 kg Mass of block B (m ) b 1.25 kg The coefficient of kinetic friction (k) = 0.45 Problem (a) Step 1: Free-body diagram
