Question

What net force is required to give a 25 kg suitcase an acceleration of 2.2 m/`s^2` to the right?

Answer 1

`55 N`

Explanation:

Using Newton's second law of motion:

`F=ma`

Force=mass `times` acceleration

`F=25 times 2.2`

`F=55 N`

So 55 Newtons are needed.

Answer 2

`55 \ "N"`

Explanation:

We use Newton's second law of motion here, which states that,

`F=ma`

• `m` is the mass of the object in kilograms

• `a` is the acceleration of the object in meters per second

And so, we get,

`F=25 \ "kg"*2.2 \ "m/s"^2`

`=55 \ "N"`
