Physics - W.E.P. Question with Solution | TestHub

A body of mass $m=4\mathrm{kg}$ starts moving with velocity $v_0$ in a straight line in such a way that on the body, work is being done at the rate which is proportional to the square of velocity as given by $\mathrm{P}=\beta {\mathrm{v}}^2$ where $\beta =\frac{0.693}{2}$. Find the time elapsed in seconds before velocity of body is doubled.
