what is the mass of an object if a net force of 8.0 n causes it to accelerate at 1.1 m/s²?\n6.9 kg\n7.3 kg\n8.8 kg\n9.1 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 $m=\frac{F}{a}$.
Step2: Substitute given values
Given $F = 8.0\ N$ and $a=1.1\ m/s^{2}$, then $m=\frac{8.0}{1.1}\ kg$.
Step3: Calculate the mass
$m=\frac{8.0}{1.1}\approx7.3\ kg$.
Answer:
B. 7.3 kg
