Resultant force and F = ma

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

A 2.0 kg block is pushed along a horizontal floor with a constant horizontal force of 10 N. The frictional force on the block is 4.0 N. Using Newton’s second law, calculate the acceleration of the block.

$3.0\,\text{m/s}^2$
$2.0\,\text{m/s}^2$
$5.0\,\text{m/s}^2$
$7.0\,\text{m/s}^2$
