In the figure, a uniform plank, with a length L of 4.75 m and a weight of 630 N, rests on the ground and against a frictionless roller at the top of a wall of height h = 2.36 m. The plank remains in equilibrium for any value of θ = 70.0∘ or more, but slips if θ < 70.0∘. Find the coefficient of static friction between the plank and the ground. Number Units

In the figure, a climber with a weight of 390 N is held by a belay rope connected to her climbing harness and belay device; the force of the rope on her has a line of action through her center of mass. The indicated angles are θ = 35∘ and φ = 35∘. If her feet are on the verge of sliding on the vertical wall, what is the coefficient of static friction between her climbing shoes and the wall? μS = Number Units

A uniform ladder of mass mL = 12.3 kg and length L = 3.80 m is leaned against a frictionless wall at an angle of θ = 23.4∘, as shown in Figure 2. A human, of mass mh = 83.8 kg, stands a distance d = 1.10 m up the ladder as shown. What is the minimum coefficient of static friction between the ladder and the ground that will prevent the ladder from slipping?

A block of mass m sits on top of a slab of mass 4 m. The slab rests on a frictionless floor. The coefficient of static friction between the slab and the block is 0.60 whereas the coefficient of kinetic friction is 0.40 . The block is now pulled by a horizontal force of magnitude F to the left. (a) It is observed that the blocks move together as a system. In this case, is the friction between the contact surfaces of the block and the slab static friction or kinetic friction? Justify. (b) If m = 10 kg, what is the maximum value of the applied horizontal force, F for which the slab and the block move together as a system? (c) If the applied horizontal force is increased beyond the value you determined in part (b), describe what would be the change, if any, in the motion of the block and slab. Explain. (d) For F = 100 N, what would be the accelerations of the slab and the block individually if you expect them to be different?
