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? A) 0.392 m/s² B) 1.96 m/s² C) 3.12 m/s² D) 5.35 m/s² E) 0.00 m/s²

We can use the following steps to determine the acceleration of the blocks:
1. Draw a free-body diagram for each block. 
2. Apply Newton's second law in both the x and y directions for each block. 
3. Use the fact that the acceleration of the system is the same for both blocks. 
4. Substitute in values and solve for the acceleration.

Using this method, we find that the acceleration of the blocks is 0.392 m/s^2.
