Work Power And Energy

A lift of mass \(\mathrm{M}=500 \mathrm{~kg}\) is descending with speed of \(2 \mathrm{~ms}^{-1}\). Its supporting cable begins to slip thus allowing it to fall with a constant acceleration of \(2 \mathrm{~ms}^{-2}\). The kinetic energy of the lift at the end of fall through to a distance of \(6 \mathrm{~m}\) will be _____________ \(\mathrm{kJ}\).
