Show Worked Solution

Worked Solution

Step 1: Identify the force involved (Friction). Step 2: Friction opposes motion; more friction equals less distance travelled. Step 3: Sandpaper has a rougher surface than glass, plastic, or polished wood. Step 4: Therefore, sandpaper exerts the most friction, resulting in the shortest distance.

Correct answer: Sandpaper
