    A body of mass M hits normally a rigid wall with velocity v and bounces back with the same velocity. The impulse experienced by the body is                                                                                        [AIPMT (S) 2011]

    A)  1.5 Mv

    B)       2 Mv   

    C)  zero                 

    D)       Mv
