The force P is applied to the 59-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=207 N, and (c) P=305 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 µs - 0.20 and Uk - 0.17, respectively. The friction force positive if up the incline, negative if down the incline. 59 kg 13° 22° H₂=0.20 P = 0.17

surface on the block if (a) P = 0, (b) P = 207 N, and (c) P=305 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 s-0.20 and Uk - 0.17, respectively. The friction force is
positive if up the incline, negative if down the incline.
