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 the net force, $m$ is the mass, and $a$ is the acceleration.

Step2: Rearrange the formula to solve for mass

$m=\frac{F}{a}$

Step3: Substitute given values

Given $F = 45\ N$ and $a=3.0\ m/s^{2}$, then $m=\frac{45}{3.0}=15\ kg$

Answer:

$15\ kg$
