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).
