A block slides with velocity of $10 \mathrm{~m} / \mathrm{s}$ on a rough horizontal surface. It comes to rest after covering a distance of $50 \mathrm{~m}$. If $g$ is $10 \mathrm{~m} / \mathrm{s}^{2}$, then the coefficient of dynamic friction between the block and the surface is a. $0.1$ b. 1 c. 10 d. 5
