<p>A lift of mass M = 500 kg is descending with speed of 2&nbsp;<span class="equation">\(ms^{-2}\)</span>&nbsp;. Its supporting cable begins to slip thus allowing it to fall with a constant acceleration of 2&nbsp;<span class="equation">\(ms^{-2}\)</span>&nbsp;The kinetic energy of the lift at the end of fall through to a distance of 6m will be____kJ​​​​​​​</p>
