Two blocks of equal mass mA=mB= 4.75 kgkg are connected by a rope over a frictionless pulley, as shown in the figure. Block B begins to fall and pulls Block A up the incline. Block A is on a rough incline with the coefficient of kinetic friction of μk =0.10 between the block and the incline. The angle of the incline is θ=30°.

a) Calculate the normal force on block A.

b) Calculate the frictional force on block A from the incline.

c) Calculate the magnitude of the blocks acceleration.

d) Calculate the tension in the rope.
