what is the mass of a falling rock if it produces a force of 147n? the acceleration rate for gravity is 9.8 m/s2.
Answer
Explanation:
Step1: Recall Newton's second law
$F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration. We want to find $m$, so we can rewrite the formula as $m=\frac{F}{a}$.
Step2: Substitute given values
Given $F = 147N$ and $a=9.8m/s^{2}$. Then $m=\frac{147}{9.8}$.
Step3: Calculate the mass
$m = 15kg$.
Answer:
$15kg$
