Squid Propulsion

Squid usually move by using their fins, but they can utilize a form of “jet propulsion,” ejecting water at high speed to rocket them backward, as shown in Figure II.1 . A 4.0 kg squid can slowly draw in and then quickly eject 0.30 kg of water. The water is ejected in 0.10 s at a speed of 10 m/s. This gives the squid a quick burst of speed to evade predators or catch prey.

What is the speed of the squid immediately after the water is ejected?

A. 10 m/s

B. 7.5 m/s

C. 1.3 m/s

D. 0.75 m/s
