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 ? ?

y Problem 3: The diagram shows the all of the forces acting on a body of mass 2.31 kg. The three forces have magnitudes F₁ = 50.6 N, F2 = 20.8 N, and F3 = 75.8 N, with directions as indicted in the diagram, where 0 = 39.6 degrees and p = 30.1 degrees. The dashed lines are parallel to the x and y axes. At t = 0, the body is moving at a speed of 7.93 m/s in the positive x direction. Part (a) What is the x component of the acceleration in m/s²? ax = || Ę Lª F $ F
