Worked Solution
Step 1: Friction opposes motion and slows down moving objects.
Step 2: Rougher surfaces create more frictional force.
Step 3: Sandpaper is the roughest surface among the options.
Step 4: More friction causes the block to stop sooner, travelling the shortest distance.
Correct answer: Sandpaper
