    A cylinder of mass 10kg is sliding on a plane with an initial velocity of 10m/s. If coefficient of friction between surface and cylinder is 0.5, then before stopping it will describe                      [Pb. PMT 2001]

    A)             12.5 m

    B)               5 m

    C)             7.5 m  

    D)             10 m

    Correct Answer: D

    Solution :

                    \[s=\frac{{{u}^{2}}}{2\mu g}=\frac{10\times 10}{2\times 0.5\times 10}=10\,m\]
