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 large block on the small block?
a.
0.40 N to the left
b.
0.80 N to the right
c.
0.40 N to the right
d.
0.80 N to the left
e.
1.20 N to the left
