Block A has a weight of 7 lb and block B has a weight of 6 lb. They rest on a surface for which the coefficient of kinetic friction is mu = 0.25. The spring has a stiffness of k= 23 lb/ft, and it is compressed 0.2 ft. (Figure 1) Part A: Determine the acceleration of block A just after both of them are released.

Question

Block A has a weight of 7 lb and block B has a weight of 6 lb. They rest on a surface for which the coefficient of kinetic friction is mu = 0.25. The spring has a stiffness of k= 23 lb/ft, and it is compressed 0.2 ft. (Figure 1)

Part A: Determine the acceleration of block A just after both of them are released.

Express your answer to three significant figures and include the appropriate units. Enter positive value if the acceleration is to the right and negative value if the acceleration is to the left.
 
Part B: 
Determine the acceleration of block B just after both of them are released.
Express your answer to three significant figures and include the appropriate units. Enter positive value if the acceleration is to the right and negative value if the acceleration is to the left.
