Answer
Explanation:
Step1: Recall Newton's second - law formula
$F = ma$, 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 $F = 1000.0\ N$ and $a = 9.8\ m/s^{2}$, then $m=\frac{1000.0}{9.8}\approx102\ kg$.
For the second question: Newton's second - law is $F = ma$. When $F$ is constant, $a=\frac{F}{m}$. As $m$ increases, $a$ decreases and vice - versa. So acceleration and mass are inversely proportional.
Answer:
- D. 102 kg
- A. Inverse
