Show Worked Solution

Worked Solution

Step 1: Identify that friction opposes motion. Step 2: Rougher surfaces like sandpaper exert more frictional force. Step 3: More friction causes the block to slow down and stop over a shorter distance. Step 4: Therefore, sandpaper results in the shortest distance.

Correct answer: Sandpaper
