The coefficients of static and kinetic friction between the 89-kg block and the inclined plane are 0.34 and 0.27 respectively. Determine (a) the friction force F acting on the block when P is applied with a magnitude of 137 N to the block at rest, (b) the force P required to initiate motion up the incline from rest, and (c) the friction force F acting on the block if P = 612 N. The friction force Fis positive if it acts up the incline and negative if it acts down the incline.
