Two blocks are accelerated across a horizontal frictionless surface as shown. Frictional forces keep the two blocks from sliding relative to each other, and the
two move with the same acceleration. If F = 1.2 N and M-1.0 kg, what is the horizontal component (frictional force ) of the force of the small block on the large block?

0.48 N to the right
b. 0.72 N to the right
c. 0.72 N to the left
d. 0.48 N to the left
e. 0.65 N to the left
