    A body moves from rest with a constant acceleration. Which one of the following graphs represents the variation of its kinetic energy K with the distance travelled x ?

    A)                      

    B)            

    C)                                              

    D)

    Correct Answer: C

    Solution :

                                When body moves under action of constant force then kinetic energy acquired by the body \[K.E.=F\times S\]             \ KE µ S  (If F = constant)             So the graph will be straight line.
