Textbook Question

Chapter P.2, Problem 16P

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

Chapter P.2, Problem 16P, Squid Propulsion Squid usually move by using their tins, but they can utilize a form of jet

This form of locomotion is speedy, but is it efficient? The energy that the squid expends goes two places: the kinetic energy of the squid and the kinetic energy of the water. Think about how to define “what you get" and “what you had to pay"; then calculate an efficiency for this particular form of locomotion. (You can ignore biomechanical efficiency for this problem.)
