An object with a mass of 20 kg has a net force of 80 n acting on it. what is the acceleration of the object?
o 0.25 m/s2
o 4 m/s2
o 60 m/s2
o 100 m/s2

The acceleration of the object is 4 m/s²

Explanation:

Newton's Second Law, also called the Fundamental Law of Dynamics, indicates that: "The change of motion is directly proportional to the printed driving force and occurs along a straight line along which that force is printed." This means that the acceleration of a moving object depends on the amount of force applied at a given time, in order to modify its trajectory or speed.

In summary, this law establishes that the net force applied to a body is proportional to the acceleration that body acquires. The constant of proportionality is the mass of the body, and this law can be expressed as:

F = m * a

where:

In this case it is necessary to know the acceleration, then:

An object with a mass of 20 kg has a net force of 80 N acting on it. So,

Replacing:

Knowing that N is a unit of measure that is obtained as kg * m/s²:

a= 4 m/s²

The acceleration of the object is 4 m/s²

Explanation:

By Applying Newton's second law of motion

Force = mass * acceleration
