360853 Water is filled in a uniform fixed container of area of cross section ' \(A\) '. A hole of cross section area ' \(a\) ' is made in the container at a height of \(20 \mathrm{~m}\) above the base. Water streams out horizontally and hits a small block placed at some distance from the container. With what speed (in \(\mathrm{ms}^{-1}\) ) the block should be moved such that water streams always hits the block.
