**1. Consider a rectangular water tank with a length of 8m, a width of 4m , and a height of 5m. Water exits the tank by pouring over the sides.**

a) If the tank is initially full of water, find the work required to empty the tank.

b) If the tank is initially half-full of water, find the work required to empty the tank.

c) If the tank is initially full of water, find the work required to pump out half of the water

d) If the tank is initially full of water, find the work F(y) required to pump out the water until the depth of water in the tank is y. Plot F(y)

e) If your goal is to pump out all of the water, at which water level y0 will half of the work be done?
