Two particles, A and B, with masses 2m and m respectively, are attached to the ends of a light inextensible string of length 4l, which passes over a small smooth peg positioned at a height of 3l from an inelastic table. The system is released from rest, with each particle initially at a height of a from the table.
1
The momentum of B when A strikes the table is m√ (8ag / 3)
2
The time that elapse before A first hit the table is v / 3g
3
The time for which A is resting on the table after the first collision & before it is first jerked off is v/ 2g
4
The time for which A is resting on the table after the first collision & before it is first jerked off is 1.5 v/g
