Physics · Secondary 3 · Hard · Resultant force and F = ma

A car of mass 900 kg accelerates uniformly from rest to a speed of 20 m/s in 8.0 s. Using Newton’s second law, what is the resultant force acting on the car?

$2.3 \times 10^3\,\text{N}$
$1.1 \times 10^3\,\text{N}$
$7.2 \times 10^3\,\text{N}$
$3.6 \times 10^4\,\text{N}$
