Using Newton's 2nd law, we know that
[tex]F_{net} = ma[/tex]
where [tex]F_{net}[/tex] = net force, m = mass of object, and a = acceleration.
We are told that the mass of the car is 1890 kg and the acceleration is 13.5m/s^2. Plug these values into the equation and solve for net force:
[tex]F_{net} = ma\\
F_{net} = (1890 kg)(13.5m/s^2)\\
F_{net} = 25515 \: N
