(1 point) The trough in the figure below has width \( w=3 \mathrm{ft} \), length \( L=12 \mathrm{ft} \) and height \( h=5 \mathrm{ft} \). (Click on the graph for a larger version.) If the trough is full of water. find the force of the water on a triangular end. (Use the density of water \( =62.4 \mathrm{lb} / \mathrm{ft}^{3} \).) Force \( = \) Don't forget to enter units. Find the work to pump all of the water over the top of the trough. Work \( = \) Don't forget to enter units
