You seem to be asking what coefficient to allow your feet to slip on the floor. You wrote, "not to accelerate."

Is that correct?

Î¼g < 0.2g
Î¼ < 0.2 will let the train slide under you untill the back of the car strikes you, or if the car is open, you fall off.

f(friction) = mew N
mew = f/N
= 0.2g / (m)(g)
=0.2/m
