You were power-washing your deck and accidentally knocked over a pot of flowers. The flowerpot is cubic in shape, each side 30 cm in length. The outlet of the power-washer is 20 mm in diameter, and according the manual, the water exits at a velocity of 5 m/s. Assume you hit the flowerpot directly in the centre of one face, knocking it over backwards. What is the maximum weight of the flowerpot?
