Worked Solution
Step 1: Identify that friction is the force that opposes the motion of the block.
Step [2-9]: A higher pulling force is required to overcome a higher frictional force.
Step [2-9]: Compare the forces: Surface Y requires 4.2N, which is the highest value in the table.
Final Answer: Surface Y.
Correct answer: Surface Y
