AI Generated Solution

To determine which object, a stone or a pencil, will reach the ground first when dropped simultaneously from the top of a tower in a vacuum, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Environment**: - The scenario specifies that both the stone and the pencil are dropped in a vacuum. In a vacuum, there is no air resistance or drag acting on the objects. 2. **Acceleration Due to Gravity**: ...
