Question

question 9 (1 point) a net force of 125 n is applied to a certain object. as a result, the object accelerates with an acceleration of 24.0 m/s². the mass of the object is

a) 0.200 kg
b) 5.21 kg
c) 2880 kg
d) 144 kg
e) 3000 kg

Explanation:

Step1: Recall Newton's second - law formula

According to Newton's second law, $F = ma$, where $F$ is the net force, $m$ is the mass, and $a$ is the acceleration. We need to solve for $m$, so $m=\frac{F}{a}$.

Step2: Substitute the given values

Given $F = 125\ N$ and $a=24.0\ m/s^{2}$. Then $m=\frac{125}{24.0}\ kg$.

Step3: Calculate the mass

$m=\frac{125}{24.0}\approx5.21\ kg$.

Answer:

B. 5.21 kg
