## 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 car in km/h.**. Any help with this is appreciated greatly, thank you.

Is it possible to find km/h from K.E

## Homework Equations

I know that KE = .5mv²

lets say the mass = 1165 kg and the K.E = 479609.6

## The Attempt at a Solution

411.682 = 479609.6 / 1165

20.289 = sqr (479609.6)

10.144 m/s² = 20.289 / 2

36.532 km/h = 10.144 / .2777
