Two blocks, stacked one on top of the other, can move without friction on the horizontal surface shown in the figure.(Figure 1) The surface between the two blocks is rough, however, with a coefficient of static friction equal to 0.45.
a. If a horizontal force F is applied to the 5.0-kg bottom block, what is the maximum value F can have before the 2.0-kg top block begins to slip?
b. If the mass of the top block is increased, does the maximum value of F increase, decrease, or stay the same? If the mass of the top block is increased, does the maximum value of increase, decrease, or stay the same?
increases
decreases
stays the same
pls explain the answers I need to know how and where the numbers come from. TIA
