Answer:
[tex]v_{squid} = 0.4\,\frac{m}{s}[/tex] in the negative direction.
Explanation:
The physical modelled is analyzed by using the Principle of Moment Conservation and Impact Theorem. Let consider that fluid travels in the positive direction:
[tex]F\cdot \Delta t = m_{fluid}\cdot v_{fluid}-m_{squid}\cdot v_{squid}[/tex]
Now, the recoil velocity of the squid is obtained
[tex]v_{squid}= \frac{m_{fluid}\cdot v_{fluid}-F\cdot \Delta t}{m_{squid}}[/tex]
[tex]v_{squid}=\frac{(0.250\,kg)\cdot (10\,\frac{m}{s} )-(5\,N)\cdot(0.1\,s)}{5\,kg}[/tex]
[tex]v_{squid} = 0.4\,\frac{m}{s}[/tex]
