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. $(g = 10\,\,m/{s^2})$ ........ $m$

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. $(g = 10\,\,m/{s^2})$ ........ $m$
Kinetic energy of the cylinder will go against friction
$\therefore \frac{1}{2}m{v^2}$=$\mu \;mgs$
$⇒$ $s = \frac{{{u^2}}}{{2\mu \;g}} = \frac{{{{(10)}^2}}}{{2 \times (0.5) \times 10}} = 10\,m$
