Advanced PhysicsQ&A LibrarySquids are the fastest marine invertebrates, using a powerful set of muscles 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 0.105 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.Question

Squids are the fastest marine invertebrates, using a powerful set of muscles 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 0.105 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.

Step 1

Let the initial momentum of the water - squid system be denoted as *p*_{i} and let the final momentum of the water - squid system be denoted as *p*_{f}.

Let the speed of ejection of water be denoted as *v*_{w} , let the speed of the squid be denoted as *v*_{s }.

Let the mass of water ejected be denoted as *m*_{w }, let the mass of the squid be denoted as *m*_{s}.

Use the Law of conservation of momentum as follows.

Step 2

As initially the water – squid system is at rest substitute 0 for *p*i and further express *p*f as,
