A Rectangular Plate, Having a Height of Two Metres and a Width

Short Answer

A rectangular plate, having a height of two metres and a width of five metres is submerged vertically such that its top edge is three metres below the surface of the water. Determine the force of the water acting on the plate to three significant digits. Recall that the mass density of water is $1000 \mathrm{~kg} / \mathrm{m}^{3}$ and that gravity is $9.8 \mathrm{~m} / \mathrm{s}^{2}$ .
