Physics · Secondary 3 · Medium · Friction and air resistance

A 2.0 kg block is pulled along a horizontal table by a 12 N force. The frictional force opposing the motion is 4.0 N. What is the acceleration of the block?

$2.0\,\text{m/s}^2$
$3.0\,\text{m/s}^2$
$4.0\,\text{m/s}^2$
$6.0\,\text{m/s}^2$
