"an open tank has the shape of a right circular cone. the tank is 6 feet across the top and 5 feet high. how much work is done in emptying the tank by pumping the water over the top edge? note: the density of water is 62.4 lbs per cubic foot."

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
