  • question_answer
    In the above question, if another body is at rest, then velocity of the compound body after collision is

    A)             v/2      

    B)             2v

    C)             v         

    D)             Zero

    Correct Answer: A

    Solution :

                    If initially second body is at rest then Initial momentum = \[mv\] Final momentum = 2mV By conservation of momentum \[2mV=mv\] Þ \[V=\frac{v}{2}\]
