Worked Solution

Step 1: Identify the environment (vacuum = no air resistance). Step [2-9]: Understand that gravity pulls all objects at the same rate of acceleration regardless of mass when air resistance is absent. Step [2-9]: They reach the ground simultaneously.

Correct answer: Both hit the ground at the same time because gravity acts on both.
