An open tank has a vertical rectangular gate as a partition, and on one side contains gasoline. The rectangular gate, that is 5 m high and 2 m wide, is hinged at the bottom end of the partition. A stopper is located at the top end of the gate, which only allows the gate to swing open towards the gasoline side of the tank. Water is slowly added to the empty side of the tank. If the depth of the gasoline is 4.5 m, determine the depth of the water when the gate is about to open.
