    A body projected with an initial velocity horizontally has kinetic energy K. If it is projected at an angle \[45{}^\circ \] the initial kinetic energy will be:

    A)  0.7 K                    

    B)         1.41 K                  

    C)  2K                         

    D)         K

    Correct Answer: D

    Solution :

    The relation of kinetic energy \[{{E}_{Ki}}=\frac{1}{2}m{{v}^{2}}\] So, it depends only on its initial speed \[v\] and it does not depend on the directions of projection. Therefore, the kinetic energy will remain same.
