Squids and octopuses propel themselves by expelling water. They do this by taking the water into a cavity and then suddenly contracting the cavity, forcing the water to shoot out of an opening. A 6.40 kg squid (including the water in its cavity) that is at rest suddenly sees a dangerous predator.
Part 1: If this squid has 1.90 kg of water in its cavity, at what speed must it expel the water to suddenly achieve a speed of 2.65 m/s to escape the predator? Neglect any drag effects of the surrounding water.
Part 2: How much kinetic energy does the squid create for this escape maneuver?
The block of mass M slides back along the horizontal surface with a coefficient of kinetic friction mk and eventually comes to a rest. In terms of v4, how far does the block slide during this final leg of its journey
