Answer :

1 m/s^2
Because of
F=ma

Answer:

It would have an acceleration of [tex]1\frac{m}{s^{2}}[/tex]

Explanation:

Let's start defining the newton unit (Newton : N)

The N definition is

[tex]N=Kg.(\frac{m}{s^{2}})[/tex]

Where Kg is kilogram and [tex]\frac{m}{s^{2}}[/tex] is an acceleration unit.

We can think the definition of newton as :

Given an object with a mass of 1 Kg subjected to a force of 1 N the acceleration that it experiments is [tex]1\frac{m}{s^{2}}[/tex]

As a result, the standard  kilogram bar kept in Paris will experiment an acceleration of [tex]1\frac{m}{s^{2}}[/tex] If we subject it to a net force of 1 N.
