Question

Squids arc aquatic creatures that use jet propulsion for motion^5 Taking up water in their main cavity, they eject it out of a siphon, which can he oriented in many different directions. A 0.20-kg squid has a cavity that holds 68 mL of water. When the squid needs to move, the cavity volume decreases by 40% and the expelled water allows the squid to attain a maximum velocity of 1.25 m/s. Assume that the squid shoots water out of its siphon at 6.7 g/s at a velocity of 3.8 m/s. What is the magnitude of the external force that would be required to keep the squid from accelerating? The magnitude of the force required to keep the squid in steady state is N (round to the nearest thousandths).

Explanation / Answer

F= Qv . Given Q= .0067 kg/s .
And v= 3.8m/sec . Therefore
F=0.02546N
