Question

The force P is applied to the 51-kg block when it is at rest. Determine the magnitude and direction of the friction force exerted by the surface on the block if (a) P = 0, (b) P = 178 N, and (c) P = 228 N. (d) What value of P is required to initiate motion up the incline? The static and kinetic coefficients of friction between the block and the incline are μ_s = 0.20 and μ_k = 0.15, respectively. The friction force is positive if up the incline, negative if down the incline. Kindly give a detailed solution, thank you!
