Re: 4 newtons of force???

Otherwise known as F=ma

If you have a mass of 2kg, then this means you need an acceleration of 2m/s^2

Now, you assume that you are working with a free floating object (no friction/gravity), and approximately 1/4" or 0.0063m of stopping distance (based on the rules).

This means, that you need to solve for u, or initial velocity in this formula.

v=final velocity=0
u=initial velocity=unknown
a=acceleration=2
s=distance traveled=0.0063

v^2 = u^2 + 2as

Based on that I am coming up with about 0.16m/s
Now, this is actually low, due to the fact that the calculation I just did is ignoring gravity.

I am using a formula from

So, I dunno if it is correct, but it sounds about right. Admittedly, I need to brush up on Newtonian physics
