Answer:
The net force used on the box was 480 N
Explanation:
Mechanical Force
According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:
F = ma
Where a is the acceleration of the object.
The mass of a box is m=200 kg and it's accelerated at a=2.4\ m/s^2 by a net force whose magnitude is:
F = 200 * 2.4 N
F = 480 N
The net force used on the box was 480 N
