    A particle of mass m moving with velocity v strikes a stationary particle of mass 2 m and sticks to it. The speed of the system will be:

    A)  \[3\upsilon \]                                   

    B)  \[\upsilon /3\]                 

    C)  \[2\upsilon \]                   

    D)         \[\upsilon /2\]

    Correct Answer: B

    Solution :

    Applying law of conservation of momentum \[m\upsilon =(m+2m)\,{{\upsilon }_{1}}\] so,          \[{{\upsilon }_{1}}=\frac{\upsilon }{3}\]
