Worked Solution
Step 1: Understand that friction opposes motion.
Step 2: A greater frictional force will cause the block to stop sooner, resulting in a shorter distance travelled.
Step 3: Surface Z has the shortest distance (8 cm), meaning it exerted the greatest friction.
Correct answer: Surface Z (8 cm)
