Some species of jellyfish use jet propulsion to get around, a much gentler form of jet propulsion than squid use. A small jellyfish takes water into its bell; the total mass of jellyfish and water is 3.2 gg. The jellyfish then rapidly ejects 1.3 gg of water, achieving a speed of 0.070 m/sm/s. What is the speed of the ejected water?
