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

A 0.50 kg block is pushed across a horizontal table by a constant horizontal force of 6.0 N. The frictional force opposing the motion is 2.0 N.

What is the acceleration of the block?

$2.0\,\text{m s}^{-2}$
$4.0\,\text{m s}^{-2}$
$6.0\,\text{m s}^{-2}$
$8.0\,\text{m s}^{-2}$
