Two men of masses M and `M+m` start simultaneously from the ground and climb with uniform accelerations up from the free ends of a massless inextensible rope whick passes over a smooth pulley at a height h from the ground.
(a) Which man reaches the pulley first?
(b) If the mam who reaches first takes time t to reach the pulley, then find the distance of the second man from the pulley at this instant.
