The base unit of length in the international system of units is the: meter (m)
<h3>Meter</h3>
The meter, ( symbol: m ) is the SI unit of length. It is derived by taking the fixed numerical value of the speed of light in vacuum c to be 299 792 458 when expressed in the unit m s-1
<h3>International system of unit ( SI ) base units</h3>
The SI base units are the standard units of measurement defined which is defined by the International System of Units (SI) for the seven base quantities of what is now known as the International System of quantities:

Answer:
0.39
Explanation:
In order not to slide, you must have exactly the same acceleration of the train:
where
g = 9.81 m/s^2
There is only one force acting on you: the static frictional force that "pulls" you forward, and it is given by
According to Newton's second law, the net force acting on you (so, the frictional force) must be equal to your mass times the acceleration, so we have
from which we find
so, the minimum coefficient of static friction must be 0.39.
