Six identical blocks – numbered 1 to 6 – have been glued in two groups of three each and have been suspended over a pulley as shown in fig. The pulley and string are massless and the system is in equilibrium. The block 1, 2, 3, and 4 get detached from the system in sequence starting with block 1. The time gap between separation of two consecutive block (i.e., time gap between separation of 1 and 2 or gap between separation of 2 and 3) is `t_(0)`. Finally, blocks 5 and 6 remain connected to the string.
(a) Find the final speed of blocks 5 and 6.
(b) Plot the graph of variation of speed of block 5 with respect to time, Take t = 0 when block 1 gets detached.
