  • question_answer
    The velocity of a body depends on time according to the equation \[v=20+0.1{{t}^{2}}\]. The body is undergoing [MNR 1995; UPSEAT 2000]

    A)             Uniform acceleration  

    B)             Uniform retardation

    C)             Non-uniform acceleration       

    D)             Zero acceleration

    Correct Answer: C

    Solution :

                    Acceleration \[a=\frac{dv}{dt}=0.1\times 2t\]\[=0.2t\]             Which is time dependent i.e. non-uniform acceleration.
