Three blocks are attached via a cord over two massless pulleys. Bricks 1 and 3 hang outside the table on either side, while block 2 is on the table. The coefficients of friction between block 2 and the table is µs = 0.3 and µk = 0.2. The blocks have the masses: ?1 = 1 ??, ?2 = 5 ??, ?3 = 4 ?? a) Draw a free-body diagram for each of the blocks and calculate the acceleration of the blocks. b) What is the total kinetic energy of the system after block 3 has fallen a distance Δℎ = 0.5 ? ?
