Worked Solution

CLAIM: Friction acts in the opposite direction to the motion of the box. EVIDENCE: Ravi pushes the box forward, but friction acts backward. REASONING: Friction is a contact force that opposes the relative motion between two surfaces. Since the box moves forward, friction acts backward to resist this motion.

Correct answer: Friction acts in the opposite direction to the motion of the box.
