    Shape of graph between speed and kinetic energy of the body is

    A) hyperbola                          

    B) straight line

    C) parabola     

    D) circle

    Correct Answer: C

    Solution :

    Kinetic energy \[K=\frac{1}{2}m{{v}^{2}}\] \[\Rightarrow \]\[K\propto {{v}^{2}}\] Comparable to equation of parabola \[{{y}^{2}}=4ax\] Hence, graph is parabolic in shape.
