Answer:

B 1500N

Explanation:

The acceleration of the car - at least the average one, but that will do, is [tex]a= \frac{\Delta v}{\Delta t} = \frac 53 ms^{-2} = 1.66 ms^{-2}[/tex]

We know the acceleration, we know the force, let's drop them in Newton second law.

[tex]F= ma = 2500= m \frac53 \rightarrow m=500\times 3 N = 1500N[/tex]
