141742 A block slides with a velocity of \(10 \mathrm{~m} / \mathrm{sec}\) on a rough horizontal surface. It comes to rest after covering a distance of \(50 \mathrm{~m}\). If \(\mathrm{g}\) is \(10 \mathrm{~m} / \mathrm{sec}^{2}\), then the coefficient of dynamic friction between the block and surface is
