Extracted text: 6/4 The coefficients of static and kinetic friction between the 100-kg block and the inelined plane are 0.30 and 0.20, respectively. Determine (a) the friction force F acting on the block when P is applied with a magni- tude of 200N 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 600 N. 100 kg 20 H = 0.30 Hl =0.20 15°
