Calculating the Pulling Force of a 2t Car Over 100m in 10s

[Makara]

Homework Statement

A car with mass of 2t, from starting point travels a distance of 100m for 10s. How much is the pulling force of the car?

Which means that:
m=2t=2000kg
s=100m
t=10s

F-pulling=?

How to find it? :P

Newton's second law, says that F = m a, where a is the acceleration (I assume it is taken to be constant).

How can you find the acceleration from the given data?
