A 800 kg car zooms away from a red light with an acceleration of 7.6 m/s2. What is the average net force in Newtons that the car experiences?

Fnet = 13920 Newtons

Explanation:

Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.

Mathematically, net force is given by the formula;

Where;

Given the following data;

Mass, m = 800 kg

Acceleration, a = 7.6m/s²

To find the applied force;

Substituting into the equation, we have;

Fapp = 6080N

To find the gravitational force;

We know that acceleration due to gravity, g = 9.8m/s²

Substituting into the equation;

Fg = 7840N

To find the net force;

Substituting into the equation, we have;

Fnet = 13920 Newton.

Therefore, the net force experienced is 13920 Newton.
