Two identical...

Question

Two identical buggies each of mass $150$ kg move one after the other without friction with same velocity $4 m / s$ . A man of mass $m$ rides the rear buggy. At a certain moment, the man jumps into the front buggy with a velocity $ν$ relative to his buggy. As a result of this process, rear buggy stops. If the sum of kinetic energies of the man and the front buggy just after collision with the buggy differs from that just before collision by $2700 J$ , then the velocity $ν$ of the man relative to the buggy is

A
