Answer:
It would have an acceleration of

Step-by-step explanation:
Let's start defining the newton unit (Newton : N)
The N definition is

Where Kg is kilogram and
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

As a result, the standard kilogram bar kept in Paris will experiment an acceleration of
If we subject it to a net force of 1 N.
