Question

Cuttlefish use jet propulsion to move rapidly. To do this, a cuttlefish fills its muscular mantle cavity with water and then quickly expels the water through a tube-like opening. The mass of a cuttlefish is about the same as the mass of water of the same volume. A 16-cm-long and 6.0-cm-wide cuttlefish, initially at rest, is moving at a speed of 4.0 m/s after expelling the water from its body. Assume that the cuttlefish has a cylindrical form, the mantle cavity has a form of a cylinder with length of 9.0 cm, and the thickness of the muscle surrounding the sides of the cavity is 1.0 cm. Part A Estimate the speed of the expelled water relative to the sea bed. Express your answer with the appropriate units.
