* Acceleration due to gravity: The acceleration due to gravity (g) is constant for all objects near the Earth's surface. This means that regardless of their mass, all objects fall at the same rate.
* Neglecting friction: By ignoring friction, we're assuming there's no air resistance or other forces slowing down the masses.
Therefore, in a vacuum or a scenario where air resistance is negligible, both masses will fall 3 meters and reach the ground simultaneously.
Important Note: In reality, air resistance can significantly affect the falling time of objects, especially if they have different shapes or surface areas. A feather and a bowling ball will not fall at the same rate in the real world due to the feather's greater air resistance.
