Question

1. a net force of 45 n causes an object to accelerate at 3.0 m/s/s. what is the objects mass? step 1 step 2 step 3

Explanation:

Step1: Recall Newton's second - law formula

$F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration. We need to solve for $m$, so we can rewrite the formula as $m=\frac{F}{a}$.

Step2: Identify given values

$F = 45\ N$ and $a=3.0\ m/s^{2}$.

Step3: Substitute values into the formula

$m=\frac{45\ N}{3.0\ m/s^{2}}$.

Answer:

$15\ kg$
