A 1.50 kgkg squid (including the mass of water inside the squid) drifting at 0.40 m/sm/s suddenly ejects 0.190 kgkg of water to quickly get itself moving at 2.50 m/s..If drag is ignored over the small interval of time needed to expel the water

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 14-cm-long and 6.0-cm-wide cuttlefish, initially at rest, is moving at a speed of 4.0 m/sm/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 a length of 9.0 cm, and the thickness of the muscle surrounding the sides of the cavity is 1.0 cm. Estimate the speed of the expelled water relative to the sea bed. Express your answer with the appropriate units.

a 4.0 kg particle is moving horizontally with a speed of 5.0 m/s when it strikes a vehicle wall. The particle rebounds with the speed of 3.0 m/s . what is the magnitude of the impulse deliveed to the particle.

Q.10. A bullet of mass m = 20 g is fired horizontally into a wooden block, of mass M = 1 kg, resting on a horizontal table. The speed of the bullet just before reaching %3D the block is v, = 600 m/s. If the bullet imbeds in the block, then the speed of the (bullet, block) system immediately after the collision is: a. v = 0 b. v = 14.634 m/s %3D M c. v = 17.475 m/s d. v = 11.765 m/s m + M
