IP 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 0.44. Part 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? Express your answer using two significant figures. Πν ΑΣφ. F = N Submit Request Answer Part B If the mass of the top block increased, does the maximum value of F increase, decrease, or stay the same?
