Worked Solution
Step 1: Identify the force involved (Frictional force).Step 2: Friction opposes motion and is greater on rougher surfaces.Step 3: Sandpaper is the roughest material among the options.Step 4: Higher friction results in more kinetic energy being converted to heat, stopping the block earlier.
Correct answer: Sandpaper
