Calculate the net acceleration acting on a 40 kg box being pushed across a horizontal floor. There is a 400 N normal force, a 195 N applied force, and a 55 N force of friction resisting any sliding motion. Assume g = 10 m/s ^ 2

Net acceleration = 3.5m/s²

Explanation:

Given the following data;

Mass, m = 40kg

Normal force, Fn = 400N

Applied force, Fapp = 195N

Force of friction, Ff = 55N

Mathematically, the net force is given by the formula;

Substituting into the equation, we have;

To find the acceleration;

Making acceleration "a" the subject of formula;

Net acceleration, a = 3.5m/s²
