The force Pis applied to the 36-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 = 182 N, and (c) P = 283 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 H; = 0.32 and Hk = 0.29, respectively. The friction force is
positive if up the incline, negative if down the incline.
