A block of mass m = 100 kg is on an inclined plane as shown where ∅ = 20 degrees and θ = 40 degrees. The coefficient of static friction is μs = 0.35 and coefficient of kinetic friction is μk = 0.3 . Determine the friction force, F, acting on the block when force P with a magnitude of 200 N is applied to the block, which remains in equilibrium. Determine the magnitude of the force, P, required to initiate motion of the block up the slope from rest. Determine the magnitude of the friction force F acting on the block if P = 900 N.

(c) The block is traveling to the right with a magnitude of the applied force, |F→A| = 20 N, what is the acceleration of the block?

A small block of mass m rests on the rough, sloping side of a triangular block of block of mass M which itself rests on a horizontal frictionless table (see the figure). The rough incline surface has a coefficient of static friction μs. A) Suppose that you apply a horizontal force F to push the triangular block (see the figure). Explain what will happen to the small block if the applied force F is relatively small. You gradually increase force F, and explain what will eventually happen to the small block as the force is sufficiently large. B) Draw a free body diagram for each of the blocks m and M. What is the direction of acceleration of these two blocks when they stick and move together? How many forces act on each of the blocks m and M? How many Newton's 3rd law force pairs are there in these two free body diagrams? Set up a coordinate system fixed to the table. Is the block M an inertial frame? C) Determine the minimum horizontal force F such that the small block will start moving up the incline. Draw coordinate systems, and write down intermediate steps with equations.
