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.

Respuesta :

ANSWER:

Both objects will hit the ground at the same time

STEP-BY-STEP EXPLANATION:

By newton's laws of motion:

[tex]F=m\cdot a[/tex]

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

Therefore:

[tex]\begin{gathered} m\cdot a=m\cdot g \\ \\ a=g \end{gathered}[/tex]

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.
