Resultant force and F = ma

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

Two horizontal forces act on a 3.0 kg cart: 14 N to the right and 5.0 N to the left. What is the acceleration of the cart, and in which direction?

Use the idea of resultant force and

F = ma

$3.0\,\text{m/s}^2$ to the right
$3.0\,\text{m/s}^2$ to the left
$1.5\,\text{m/s}^2$ to the right
$4.5\,\text{m/s}^2$ to the left
