FA23 PHY 321.1

4) Two blocks are connected by a string that goes over an ideal pulley as

shown in the figure and pulls on block A parallel to the surface of the

plane. Both blocks have a mass of 3.00 kg and Block A can slide along a

rough plane inclined 30.0° to the horizontal. The coefficient of kinetic

friction between block A and the plane is 0.200. If the blocks were in

motion, what would be the acceleration of the blocks? What is the

tension in the string? Include appropriate free body and kinetic diagrams.
