Suppose a squid of mass 184 g (including the water that will be expelled) is initially at rest. It then expels 58 g of water at an average speed of 64 cm/s (relative to the surrounding water). Ignoring drag forces, how fast is the squid moving immediately after expelling the water? Only type in a numerical answer. Though the unit of the result will be in meters per second (m/s) do include the units in your answer, else the response will be counted as being incorrect.

Step 1

The total momentum of the system (squid plus water) before the water is expelled is equal to the total momentum of the system after the water is expelled. Since the squid is initially at rest, its initial momentum is 0. Show more…
