Two blocks are connected by a string that goes over an ideal pulley as shown in the
figure. Block A has a mass of 3.00 kg and can slide over a rough plane inclined 30.0° to
the horizontal. The coefficient of kinetic friction between block A and the plane is 0.400.
Block B has a mass of 2.77 kg. What is the acceleration of the blocks?
