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 tubelike opening. The mass of a cuttlefish is about the same as the mass of water of the same volume. A cmlong and cmwide cuttlefish, initially at rest, is moving at a speed of ms 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 cm and the thickness of the muscle surrounding the sides of the cavity is cm Estimate the speed of the expelled water relative to the sea bed?
