The 69-kg crate is stationary when the force Pis applied. Determine the resulting acceleration of the crate if (a) P = 0, (b) P = 239 N, and (c) P = 493 N. The acceleration is positive if up the slope, negative if down the slope. Hg = 0.25 Hk = 0.18 69 kg P 18°

Question
Part (a). We need to decide if the block moves. The easy way to make this decision is to assume that the block does not move and then to test this assumption. If P = 0, what friction force F is needed to keep the block from moving? mg F N Answer: F = i N
