Two masses m and 2m are connected by a mass less string which passes over a light frictionless pulley shown in figure-2.28. The masses are initially held with equal lengths of the strings on either side of the pulley. Find the velocity of the masses at the instant the lighter mass moves up a distance of 6.54 mts. This string is suddenly cut at that instant. Calculate the time taken by each mass to reach the ground. Take g = 9.8 m//s^(2) . [3.27 m//s^(2), 2.78 sec, 2//3 sec]
