The dependence of velocity of a body with time is given by the equation $\mathrm{v}=20+0.1 \mathrm{t}^{2}$. The body is in
  1. uniform retardation
  2. uniform acceleration
  3. non-uniform acceleration
  4. zero acceleration.

Solution

On differentiating, acceleration $=0.2 \mathrm{t}$ $\Rightarrow \mathrm{a}=\mathrm{f}(\mathrm{t})$
