    The dependence of velocity of a body with time is given by the equation \[v=20+0.\text{ }1\text{ }{{t}^{2}}\]. The body is in

    A) uniform retardation

    B) uniform acceleration

    C) non-uniform acceleration

    D) zero acceleration.

    Correct Answer: C

    Solution :

    On differentiating, acceleration = 0.2t \[\Rightarrow \text{a=f}\left( \text{t} \right)\]
