The coefficient of static friction between the wall and the block is 0.68 , and the coefficient of kinetic friction is 0.37 . Assume that the block is not moving initially. (a) Will the block move? ("yes" or "no") (b) In unit-vector notation Fxi^ + Fyj^, what is the force on the block from the wall? (a) (b) Number i^ + j^ Units

In the figure, a slab of mass m1 = 40 kg rests on a frictionless floor, and a block of mass m2 = 12 kg rests on top of the slab. Between block and slab, the coefficient of static friction is 0.60, and the coefficient of kinetic friction is 0.40. A horizontal force F→ of magnitude 109 N begins to pull directly on the block, as shown. In unit-vector notation, what are the resulting accelerations of (a) the block and (b) the slab? (a) Number i^ + j^ Units (b) Number i^ + j^ Units

The weight of the block in the drawing is 85.0 N. The coefficient of static friction between the block and the vertical wall is 0.590. (a) What minimum magnitude of the force F→ is required to prevent the block from sliding down the wall? (Hint: The static frictional force exerted by the block is directed upward, parallel to the wall.) (b) What minimum force is required to start the block moving up the wall? (Hint: The static frictional force is now directed down the wall.) (a) Number Units (b) Number Units
