Find out the distance travelled by the block as shown in figure. If the initial speed of the block is v and `mu` is the friction coefficient between the surface of block and ground.

Explanation

Applying work energy theorem, we get
`rArr " " (-mu "mg" l) = (0 + 0) - ((1)/(2) mv^(2) + 0)`
`rArr " " mu g l = (1)/(2) v^(2) " " rArr " " l = (v^(2))/(2mu g )`
