A block of mass $$m$$ is moving on rough horizontal surface with momentum $$p$$. The coefficient of friction between the block and surface is $$\mu$$. The distance covered by block before it stops is [$$g=$$ acceleration due to gravity]

$$\frac{2 \mu M^2 g}{p^2}$$

$$\frac{p}{2 \mu M g}$$

$$\frac{2 \mu M g}{p}$$

$$\frac{p^2}{2 \mu M^2 g}$$
