Show Worked Solution

Worked Solution

Step 1: Both have the same mass, so gravity pulls them equally. Step [2-9]: The crumpled ball has a smaller surface area than the flat sheet. Step [2-9]: Smaller surface area results in less air resistance, allowing it to fall faster.

Correct answer: The crumpled ball
