Question

A person of weight $70kg$, a stone of weight $1kg$ and a paper of weight $10g$ start falling at the same time on the earth from a height of $100ft$. If the air resistance is neglected, which of the following will reach the earth first?

• A. Person
• B. Stone
• C. Paper
• D. All will reach the earth at the same time

Answer 1

The correct option is D All will reach the earth at the same time

Free falling objects fall with a constant acceleration called the acceleration due to gravity $(g=9.81m{s}^{-2}$ on earth). Since air resistance is neglected, all the bodies will be in a state of free fall.

Therefore, the person, stone and paper will reach the earth in the same time.
