A squid can propel itself by taking water into its body and then expelling it. A 0.60 kg squid expels 0.30 kg of water with a velocity of 20 m/s [S]. What is the speed of the squid immediately after expelling the water?

momentum is conserved ... Mw * Vw = Ms * Vs
the squid expels water equal to half of its own mass
so the squid's velocity will be half of the water's velocity
