Squids are the fastest marine invertebrates, using a powerful set of muscies to take in and then eject water in a form of jet propulsion that can propel them to speeds of over 11.5 m/s. What speed (in m/s) would a stationary 1.60 kg squid achieve by ejecting 0.115 kg of water (not included in the squid's mass) at 3.00 m/s? Neglect other forces, including the drag force on the squid.

. The fisherman's mass is 79 kg, and the boat's is 126 kg. The fisherman and boat are initially at rest when the fisherman throws a package of mass m = 15 kg horizontally to the right with a speed of vi = 4.9 m/s. What is the velocity of the boat after the package is thrown? Neglect any resistance force from the water. (Give the magnitude in m/s, and select the correct direction from the options given.)  What is the direction of the boat?

A bullet of mass 2 kg is headed at horizontal speed 60 m/s toward a block of mass14(2 kg) = 28 kg resting on a horizontal frictionless surface. The bullet strikes the blockand comes to rest relative to the block somewhere deeply embedded inside the block.What average force did the block exert onthe bullet while it was coming to a stop insidethe block, if the stopping process took 0.04 s? 1. −200 N2. Not enough information is provided toanswer.3. −2800 N4. 3000 N5. 200 N6. 2800 N7. −3000 N8. Zero, since the bullet comes to rest relative to the block.

A little fish has mass 0.400 kg and is floating motionlessly in the water, minding its own business, when a big fish (mass 2.00 kg) comes along and swallows it whole. If the big fish was gliding along at a constant velocity of 1.25 m/s before it swallowed the little fish, what will its velocity be immediately after the "collision"? O 1.04 m/s 7.50 m/s 1.50 m/s 0.250 m/s
