Hoping for complete solutions since I’m having a hard time with this. Pls skip if unsure or not willing to answer the subitems (these are all connected for one item). Thanks in advanced! 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 lower box is 0.452 and the coefficient of static friction between the two boxes is 0.770. A. Draw the Free-Body diagram of both blocks. Set the x-axis parallel to the ramp. B. Write Newton’s 2nd law along the x and y directions for both blocks. C. What are the magnitude and direction of the frictional force on the upper box?
