(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Determine the KE of a 2000 kg car with speed = 22.3 m/s.

2. Relevant equations

E = 0.5 x 2000 x 22.3^2= 497290 Joules or 497 KJ.

3. The attempt at a solution

Above.

The car is lifted vertically and dropped from rest. Find the height from which it was released if v before hitting the ground = 22.3m/s.

Here I don't know what to do...

Thanks!
