Two masses m_(1), and m_(2) are connected by a string of length L. They are held in horizontal plane at a height H above two fixed heavy plates A and B made of different material placed on the floor. Initially distance between two masses is altL. When the masses are released under gravity they make collision with A and B with co-efficient of resitution 0.8 and 0.4 respectively. The time after collision when the string becomes tight is |
