Block ‘A’ of mass m is hanging from a vertical spring of spring constant k and is at rest. The value of m/k = 1/150SI units. Block ‘B’ also of mass m strikes the block ‘A’ with velocity ‘v’ and sticks to it. Then find the value of ‘v’ in m/s for which the spring just attains natural length. Take g=10m/s2
    Correct answer is '2'. Can you explain this answer?

    the initial extension in spring is x0 = mg/k
    Just after collision of B and A the speed of combined mass is v/2
    For the spring to just atrain natural length the combined mass must rise up by x0  =mg/k (sec fig) and come to rest
    Applying conservation of energy between initial and final states
