A system of men and trolley is shown in figure. To the left end of the string, a trolley of mass \( M \)
\( \mathrm{P} \) is connected on which a man of mass \( m \) is standing. To the right end of the string another trolley of mass \( m \) is connected on which
W a man of mass \( M \) is standing. Initially, the system is at rest. All of a sudden both the men leap upwards simultaneously with the same velocity \( u \) w.r.t. ground. Which is correct?
(1) When the men are at the highest point of their motion, the trolleys will also be instantaneously at rest.
(2) When the men are at the highest point of their motion, then the left trolley will be moving downwards.
(3) Impulse acting on both the men will be same in the given process.
(4) None of these.
