A cylinder of mass $10\,kg$ is sliding on a plane with an initial velocity of $10\,m/s$. If coefficient of friction between surface and cylinder is $ 0.5$, then before stopping it will describe ............. $\mathrm{m}$

A$12.5$

B$5$

C$7.5$

D$10$

Solution

(d)$s = \frac{{{u^2}}}{{2\mu g}} = \frac{{10 \times 10}}{{2 \times 0.5 \times 10}} = 10\,m$
