Chapter P.2, Problem 15P
Squid Propulsion
Squid usually move by using their tins, but they can utilize a form of “jet propulsion,” ejecting water at high speed to rocket them backward, as shown in Figure II.I. 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.
FIGURE II.1
What is the average forte on the water during the jet?
A. 100N
B. 30N
C. 10 N
D. 3.0N
