        For a moving particle (mass m, velocity\[\upsilon \]) having a momentum P, which one of the following correctly describes the kinetic energy of the particle?

    A)  \[\frac{{{p}^{2}}}{2m}\]                                              

    B)  \[\frac{p}{2m}\]

    C)  \[\frac{{{v}^{2}}}{2m}\]                                               

    D)  \[\frac{v}{2m}\]

    Correct Answer: A

    Solution :

                    Kinetic energy of particle \[=\frac{1}{2}m{{v}^{2}}\] \[k=\frac{{{p}^{2}}}{2m}\]                           \[(\because p<mv)\]
