A bullet of mass 0.01kg and travelling at a speed of 500m/s strikes a block of mass 2 kg which is suspended by a string of length 5m. The centre of gravity  of the block is found to rise a vertical distance of 0.1m. What is the speed(m/s) of the bullet after it emerges from the block? (g=9.8m/s2).
    Correct answer is '220'. Can you explain this answer?

    Let V be the velocity acquire by the block.


    If n' is speed of bullet on emerging out of block, then by law of conservation of momentum, we get 
    mn +M x 0 = MV +Mn'
