    One sphere collides with another sphere of same mass at rest in elastically. If the value of coefficients of restification is 1/2. Tine ratio of there speed after collision will be:

    A)  1 : 2                      

    B)         2 : 1                      

    C)  1 : 3                      

    D)         3 : 1

    Correct Answer: C

    Solution :

    Ratio of velocities after collision \[\frac{{{\upsilon }_{1}}}{{{\upsilon }_{2}}}=\frac{1-e}{1+e}=\frac{1-\frac{1}{2}}{1+\frac{1}{2}}=\frac{1}{3}=1:3\]
