Co
A 4.0-kg block is stacked on top of a 12.0-kg block, which
is accelerating along a horizontal table at a = 5.2 m/s'
(Figure 1). Let µlk = Hs = l.
Part A
What minimum coefficient of friction u between the two blocks will prevent the 4.0-kg block from sliding off?
Express your answer using two significant figures.
