Homework Statement
This is not homework, I am too old for school. I am trying to teach myself accident reconstruction. The equation I have for impact utilizes crush points. The crush points reveals an energy of 479609.6 to crush the car, so what I am trying to figure out is the speed of the...
I am trying to prove that the skid to stop formula works with vehicles of different weight, with the use of kinetic energy. I think I have proven this, but if someone would like to check this over to make sure I am correct I would appreciate it.

Homework Statement
Is it possible that a vehicle weighing 2000 kg and a vehicle weighing 13000 kg can both use the same skid to stop formula?? Does the difference in weight not come into account?

Where :
S = speed in km/h
µ = .75
d = skid distance
S = 15.9...
I do not understand vehicle deceleration.
The Attempt at a Solution
d = µg
6.687 = .7 * 9.81
d = 6.687 m/s
My question is.....is it always figured out this way when dealing with vehicles.
Can someone please tell me what I am suppose to do with c1c2 and 2b in the following equation. I do not know if I am to mulitply, divide, subtract or add.
E= L * (( a /2 ) * ( c1 + c2) + b / 6 * ( c1² + c1c2 + c2² ) + ( a² / 2b))
Where: L = 1
a=375
b=45
c1=.33
c2=.33
My answer comes...
