Verified Answer :

1 m/s^2
Because of
F=ma

Answer:

It would have an acceleration of \(1\frac{m}{s^{2}}\)

Explanation:

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

The N definition is

\(N=Kg.(\frac{m}{s^{2}})\)

Where Kg is kilogram and \(\frac{m}{s^{2}}\) 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 \(1\frac{m}{s^{2}}\)

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