A 2 kg block is kept at rest on a rough horizontal surface having coefficient of static and kinetic friction as ${\mu }_{\mathrm{s}}=0.2$ and ${\mu }_{\mathrm{k}}=0.1$ respectively. A Force $\mathrm{F}=2\mathrm{t}$ starts acting on the object (where 't' is in seconds). Find the speed ' v ' (in $\mathrm{m}/\mathrm{s}$ ) of the block at $\mathrm{t}=3\mathrm{s}$. Fill ' $2{\mathrm{v}}^{\prime }$. (Take $\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2$ )
