Question

qse 1 retest 25-26
a 5kg object experiences an acceleration of 3 m/s². what is the net force acting on the object?
10 n
5 n
15 n
30 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 values

Given $m = 5kg$ and $a=3m/s^{2}$, then $F=5\times3$.

Step3: Calculate the force

$F = 15N$.

Answer:

15 N
