Question

A small block (m1 = 4.0 kg) rests on an inclined plane (m2 = 12.0 kg, ? = 53.13?). The coeffi- cients of static and kinetic friction between the surfaces of the block and the ramp are, respectively, ?s = 0.333 and ?k = 0.200. A force F?P pushes horizontally on the inclined plane to the right, causing the system to accelerate. If the force F?P is too large, the small block will slide up the ramp, whereas, if the force F?P is too small, the small block will slide down the ramp. Ignore friction between the floor and the ramp. Assume g = 10.0 m/s2.

a.) Consider the case that F?P is so large that the block is almost about to slip UP the ramp (but doesn
