A mass of 7 kg rests on a floor with friction. One force is applied vertically downward of 23 Newtons and another force is applied in the +x direction such that it just begins to move the mass. The force of 23 Newtons is then applied vertically upwards instead of downwards and another force is applied in the +x direction which just begins to move the mass that force is 141 Newtons less than the first case. What is the coefficient of static friction?

In the figure, a slab of mass m1 = 40 kg
rests on a frictionless floor, and a block of mass
m2 = 8 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 105 N begins to pull directly on the block, as shown. In
unit-vector notation, what are the resulting accelerations of
(a) the block and...
