Hi tutor pls show complete solution.
Box final answers.

Consider the figure shown in the following figure. You are lowering
two boxes, one on top of the other, down a ramp by pulling on a rope
parallel to the surface of the ramp. Both blocks move with constant
velocity. The coefficient of kinetic friction between the ramp and the
18.0
kg
lower box is 0.452 and the coefficient of static friction between the
27.0
kg
two boxes is 0.770.
