2. Squid scaling A squid cruises through the water at steady speed by jet propulsion. Imagine two squid species that are the same shape, but squid A has 5 times the body mass of squid B. Given that they both pulse at the same frequency, by what factor would squid A be faster or slower than squid B? Note that the following equation allows for the calculation of thrust by jet propulsion: T = P(AV/At)² A T: thrust, p: density of water, V: volume of water expelled, t: time, A: area of jet opening. Answer The swimming speed of species A is 71% greater than the swimming speed of species B.
