    A ball falls from rest from a height h on to a floor and rebounds to a height h/4. The coefficient of restitution between the ball and the floor is

    A) \[\frac{1}{2}\]

    B)                                        \[\frac{1}{4}\]                   

    C)  \[\frac{1}{\sqrt{2}}\]                    

    D)        \[\frac{3}{4}\]

    Correct Answer: A

    Solution :

    The coefficient of restitution \[e=\sqrt{\frac{{{h}_{2}}}{{{h}_{1}}}}\] \[=\sqrt{\frac{h/4}{h}}=\frac{1}{2}\]
