    Acceleration-velocity graph of a particle moving in a straight line is as shown in figure. Then slope of velocity displacement graph

    A)  increases linearly.

    B)  decreases linearly.

    C)  is constant.

    D)  increases parabolically.

    Correct Answer: C

    Solution :

    Acceleration-velocity equation from the graph is:\[a=kv\] Here, k = slope of given line. This can also be written as: \[v.\frac{dv}{ds}=kv\] \[\frac{dv}{ds}=k\] ?i.e., slope of velocity-displacement equation is same as slope of acceleration-velocity equation which is constant. Hence, the correction option is [c].
