Question

If a 6 lb bowling ball and a 12 pound bowling ball are both dropped from the same height at the same time, which one will hit the ground first? Explain your answer.

Answer 1

Both objects will hit the ground at the same time

Explanation:

By newton's laws of motion:

`F=m\cdot a`

Here, we only force acting is gravitational force (Ignoring air resistance).

Therefore:

`\begin{gathered} m\cdot a=m\cdot g \\ \\ a=g \end{gathered}`

The acceleration acting on both bodies will be equal to 9.8 m/s^2 and is independent of mass. Since both objects start from the same initial conditions and acceleration is same, they will hit the ground at the same time.
