(1 point) A trough has a parabolic cross section y = ax2, where a is a constant. The height is H meters and the length is L meters. The trough is filled with water. For this problem, approximate the weight density of water to be pg = 10 Newtons per cubic meter. H me page What is the work required to pump the water over the top of the trough? Work 8(10^4) LH (H/15)(sqrt(H/a)) Newton-meters. (Your answer will involve L. H. and a.) What is the force due to hydrostatic pressure on one flat parabolic side? Force Newtons.
