In the figure, a slab of mass m1 = 40 kg rests on a frictionless floor, and a block of mass m2 = 10 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 104 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?

Two forces P Y Q act on an object of mass 14.0 kg, where Q the greater of the two forces. When both forces are directed to the left, the magnitude of the object's acceleration is 0.900 m / s2. However, when the force P heads to the left and force Q is heading to the right, the object has an acceleration of 0.400 m / s2 to the right. Find the magnitudes of the two forces P Y Q in newtons. find: P= Q=
