To solve this question first we will draw a free body diagram and then equate horizontal force and vertical force and solve the equation to get the value of frictional force.
Calculation and diagram is shown below.

Block A in the figure has mass mA = 4.20 kg, and block B has mass mB = 2.40 kg. The coefficient of kinetic friction between block B and the horizontal plane is μk = 0.520. The inclined plane is frictionless and at angle θ = 34.0°. The pulley serves only to change the direction of the cord connecting the blocks. The cord has negligible mass. Find (a) the tension in the cord and (b) the magnitude of the acceleration...

Block B, with mass 5.00 kg, rests on block A, with mass 8.00kg. There is no friction between the table and block A, but the coefficient of static friction between block A and B is 0.750. A "massless" string attached to block A passes over a frictionless pulley and block C is suspended from the other end of the string. If we want ALL the blocks moving together with the same acceleration, the largest possible mass that block C can...

Block A in (Figure 1) has mass 1.00 kg, and block
B has mass 3.00 kg. The blocks are forced together,
compressing a spring S between them; then the system is
released from rest on a level, frictionless surface. The spring,
which has negligible mass, is not fastened to either block and
drops to the surface after it has expanded. The spring has force
constant 711 N/m and is initially compressed 0.225 m from its
original length.
