A car of mass 1200 kg increases its speed from 10 m/s to 20 m/s along a straight, horizontal road. Assuming the resultant force on the car is constant, what is the work done on the car during this acceleration?

$1.8\times10^5\,\text{J}$
$6.0\times10^4\,\text{J}$
$1.2\times10^5\,\text{J}$
$2.4\times10^5\,\text{J}$
