Laws Of Motion

A block of mass \(5 \mathrm{~kg}\) is placed at rest on a table of rough surface. Now, if a force of \(30 \mathrm{~N}\) is applied in the direction parallel to surface of the table, the block slides through a distance of \(50 \mathrm{~m}\) in an interval of time \(10 \mathrm{~s}\). Coefficient of kinetic friction is (given, \(g=10 \mathrm{~ms}^{-2}\)):
