Question

What is the net force required to accelerate a 1.1 kg box at a rate of 2.8
m/s??

Answer 1

Fnet = 13.86N

Step-by-step 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;

`Fnet = Fapp + Fg`

Where;

• Fnet is the net force

• Fapp is the applied force

• Fg is the force due to gravitation

Given the following data;

Mass = 1.1kg

Acceleration = 2.8m/s²

To find the applied force;

`Fapp = ma`

Substituting into the equation, we have;

`Fapp = 1.1 * 2.8`

Fapp = 3.08N

To find the gravitational force;

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

`Fg = mg`

Substituting into the equation;

`Fg = 1.1 * 9.8`

Fg = 10.78N

To find the net force;

`Fnet = Fapp + Fg`

Substituting into the equation, we have;

`Fnet = 3.08 + 10.78`

Fnet = 13.86N

Therefore, the net force required is 13.86N
