Worked Solution

Step 1: Friction is a force that opposes the motion of one surface sliding over another. Step [2-9]: Therefore, it always acts in the direction opposite to the direction of motion or intended motion. Step [2-9]: If Ravi pushes forward, friction acts backward.

Correct answer: In the opposite direction to Ravi's push
