Physics Question from JEE Main 2023 · 31 January, Shift 1

A lift of mass $M = 500 \, \text{kg}$ is descending with a speed of $2 \, \text{m/s}$. Its supporting cable begins to slip, thus allowing it to fall with a constant acceleration of $2 \, \text{m/s}^2$. The kinetic energy of the lift at the end of fall through a distance of $6 \, \text{m}$ will be ..... kJ.
