A cylinder of 10 kg is sliding in a plane with an initial velocity of 10 m / s . If the coefficient of friction between the surface and cylinder is 0.5 then before stopping, it will cover. `(g=10m//s^(2))`

Options

A. 12.5 m
B. 5 m
C. 7.5 m
D. 10 m

Answer

D

Explanation

`s = (u^(2))/(2 mu g) = (10 xx 10)/(2 xx 0.5 xx 10) = 10`m
