    A particle is dropped from a height h. A constant horizontal velocity is given to the particle. Taking g to be constant everywhere, kinetic energy E of the particle w. r. t. time t is correctly shown in

    A)

    B)                

    C)                                        

    D)

    Correct Answer: A

    Solution :

                                As particle is projected with some velocity therefore its initial kinetic energy will not be zero.             As it moves downward under gravity then its velocity increases with time K.E. µ v2 µ t2 \[(As\,\,\upsilon \propto t)\]                   So the graph between kinetic energy and time will be parabolic in nature.
