Question:

What is the average force on the water during the jet?

A. \(100 \mathrm{~N}\)

B. \(30 \mathrm{~N}\)

C. \(10 \mathrm{~N}\)

D. \(3.0 \mathrm{~N}\)

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 \(4.0 \mathrm{~kg}\) squid can slowly draw in and then quickly eject \(0.30 \mathrm{~kg}\) of water. The water is ejected in \(0.10 \mathrm{~s}\) at a speed of \(10 \mathrm{~m} / \mathrm{s}\). This gives the squid a quick burst of speed to evade predators or catch prey.image text in transcribed
