Question

A 2.5 kg box is pulled straight to the right with a force of 16N.
Since it is sliding horizontally on a surface, what is the normal force (FN) the floor supports it with?

Answer 1

Answer:

24.5N

Explanation:

The normal force refers to the force a surface exerts on an object. In this case, the normal force (FN) is the force the floor exerts on the box. It can be calculated using:

F(N) = F(g)

Where; F(N) = normal force

F(g) = force due to gravity = 9.8m/s²

Since the force is applied on an horizontal/flat surface, F(g) = mg

F(N) = 2.5kg × 9.8m/s²

F(N) = 24.5N

Answer 2

The normal force (FN) the floor supports this box with is 24.5 Newton.

Given the following data:

• Mass of box = 2.5 kg

• Force = 16 Newton

To find the normal force (FN) the floor supports this box with:

A normal force can be defined as the force being exerted by a surface on an object such as a box.

Mathematically, the normal force is given by the formula:

$FN = mg$

Where:

• m is the mass of an object.

• g is the acceleration due to gravity.

• FN is the normal force.

We know that acceleration due to gravity (a) for a box sliding horizontally on a surface is equal to 9.8 meter per seconds square.

Substituting the given parameters into the formula, we have;

$FN = 2.5(9.8)$

Normal force, FN = 24.5 Newton.
