Squids rely on jet propulsion to move around. A 1.7 squid drifting at 0.50 suddenly expels 0.11 of water backward to quickly get itself moving forward at 2.4. If drag is ignored over the small interval of time needed to expel the water (the impulse approximation), with what speed relative to itself does the squid eject the water?
