Two Blocks Are Accelerated Across a Horizontal Frictionless Surface as Shown

question 50

Multiple Choice

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
