    A sphere of mass m is moving with constant velocity collides with another identical sphere at rest. The ratio of the velocities of spheres after collision will be: (e = coefficient of restitution)

    A) \[\frac{1-e}{1+e}\]                                         

    B)        \[\frac{e-1}{e+1}\]                         

    C)        \[\frac{1+e}{1-e}\]                                         

    D)        \[\frac{e+1}{e-1}\]

    Correct Answer: A

    Solution :

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