Answer:
<h2>800 kg</h2>
Explanation:
The mass of the car can be found by using the formula
![m = \frac{f}{a} \\](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7Bf%7D%7Ba%7D%20%20%5C%5C%20)
f is the force
a is the acceleration
From the question we have
![m = \frac{2000}{2.5} \\](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B2000%7D%7B2.5%7D%20%20%5C%5C%20%20)
We have the final answer as
<h3>800 kg</h3>
Hope this helps you
