I have unit with current speed, acceleration, distance and mass. I want to stop it directly above destination point. Question is: From what distance should it start slowing down (decrease in acceleration till it reaches deceleration ) to stop to destionation point? (ie. When should it turn off its engine (on what distance before dest) so it will glide by the inertion till it''s stopped by friction?)

This sounds suspiciously like a homework problem, aside from the usual "go to a homework help board," look up the kinematics equations. (I just did them in physics, they''re quite easy.)

what''s the friction force, which hopefuly, is constant? Otherwise, it will never slow down.

Everything is better with Metal.

from here

x = v2 / 2.a

a = friction_force / mass

so

x = v2 / (2 * friction_force / mass)

x is the distance.

I think this is correct...
