Q. A cylinder of mass $10kg$ 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
A) $12.5\ m$
B) $5\ m$
C) $7.5\ m$
D) $10\ m$
Explanation
(d) $s = \frac{u^{2}}{2\mu g} = \frac{10 \times 10}{2 \times 0.5 \times 10} = 10m$
