Question

an object with a mass of 5.0 kg accelerates 8.0 m/s² when an unknown force is applied to it. what is the amount of the force?
n

Explanation:

Step1: Identify the formula

Use Newton's second - law $F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration.

Step2: Substitute the values

Given $m = 5.0\ kg$ and $a=8.0\ m/s^{2}$, then $F=(5.0\ kg)\times(8.0\ m/s^{2})$.

Step3: Calculate the force

$F = 40\ N$.

Answer:

$40$
