Concept:In the absence of air resistance, all objects fall with the same acceleration due to gravity, regardless of their mass.
Explanation:The acceleration of a freely falling object is the acceleration due to gravity,
g.
This acceleration is independent of the mass of the object.
Both the light and heavy objects are released from the same height at the same time.
Since they have the same initial velocity, zero, and the same acceleration,
g, they cover the same distance in the same time.
Therefore, they both reach the ground at the same instant.
Answer:Both the light and heavy objects reach the ground at the same time.
