A 2 kg mass moving along a horizontal surface at 10 m/s is acted upon by a 5 N force of friction. Calculate the net force?

The net force acting on the mass is equal to 13.6 Newton.

Given the following data:

We know that the acceleration due to gravity (g) of an object on planet Earth is equal to 9.8 .

To calculate the net force:

First of all, we would determine the normal force acting on the mass.

Mathematically, the normal force is given by the formula:

Where:

Substituting the given parameters into the formula, we have;

Normal force = 19.6 Newton

To find net force:

Net force = 13.6 Newton.

Note: We subtracted because friction opposes the motion of an object and as such acts in opposite direction.

F = 20.61 N

Explanation:

Given that,

Mass of the object, m = 2 kg

It is moving with a speed of 10 m/s

It is acted upon by a 5 N of friction.

The force of gravity acts in downward direction which is given by :

W = mg

W = 2 × 10 = 20 N

5 N of force is acting in horizonal surface.

The net force is given by the resultant of two vectors as follows :

So, the net force acting on the object is 20.61 N.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
