Problem: Two blocks for masses m1 and m2 are stacked on top of each other and placed on a frictionless, horizontal surface. The surfaces between two blocks is rough and has a coeff of static friction, us. A horiz push of magnitude, F, directed to the right is applied on the bottom block.
A. Derive an expression for the maximum horizontal force, F, that can be applied on the bottom block, m1, before the top block m2, begins to slip.
B. Calculate F in Newtons (m1=5 kg) (m2=2 kg) (us=0.47)
C. If the mass of the top block is increased, what happens to the maximum value of F?
