what is the mass of a crate if a net force of 12 n gives the crate an acceleration of 0.20 m/s²?\n2.4 kg\n6 kg\n12.2 kg\n60 kg
Answer
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: Substitute given values
Given $F = 12\ N$ and $a=0.20\ m/s^{2}$, then $m=\frac{12}{0.20}$.
Step3: Calculate the mass
$m = 60\ kg$.
Answer:
D. 60 kg
