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?

Given: A homogeneous quarter-circle block (with a radius of R and a weight of W ) is supported by a rough, horizontal floor, as shown.. A force P is applied to the block at corner B. Find: For this problem: a) Determine the x-location of the normal force acting on the block by the floor. Express your answer in terms of R. b) What is the minimum coefficient of static friction between the block and ground, μs, that is required to prevent motion of the block? c) Is the block in a state of impending slipping or tipping for the value of μs found in b) above? Explain. For this problem, use: P = W.
