Squid and Octolules are propelled by expelting water, which is maintained in a body cavity. A squid of 6.5 kg (including water i
n the cavity) is at rest, when suddenly a predator is spotted.
A) If the squid has 1.6 kg of water in its cavity, how fast should it expel this water so that it reaches 2.5 m/s and escapes the predator? What is the kinetic energy of the squid after this maneuver?
