Physics · Secondary 4 · Medium · Resultant force and F = ma

A car of mass 900 kg accelerates uniformly from rest to a speed of 15 m/s in 6.0 s.

Using Newton’s Second Law and the definition of acceleration, what is the resultant force acting on the car?

$2.3 \times 10^3\,\text{N}$
$1.4 \times 10^3\,\text{N}$
$3.8 \times 10^3\,\text{N}$
$5.4 \times 10^3\,\text{N}$
