JEE MainPhysicsWork Power and EnergyNumerical+4 / −1

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

\underline{\hspace{2cm}}

\mathrm{kJ}

.
