A \(100\, \mathrm{kg}\) heavy anchor is attached to a \(20\, \mathrm{m}\) long rope. One meter of the rope weights \(1\, \mathrm{kg}\). Find the work required to raise the anchor \(20\, \mathrm{m}\) higher. The standard acceleration of gravity is \(9.81\, \mathrm{m\, s}^{-2}\). Neglect the buoyancy (the force from the Archimedes law).
