s The giant Pacific octopus (Enteroctopus dofleini) has a typical mass of 15 kg and can propel itself bymeans of a water jet when frightened. (a) If it expels water at amass rate of 2.4 kg>s and with a speed of 27 m>s, what thrust canit generate? (b) If the seawater exerts a resistive force of 18 N onthe octopus, what acceleration can it achieve? (c) If the octopusmaintains its jet propulsion for 3.0 s, what maximum velocitycan it attain?
