Squid use jet propulsion for rapid escapes. A squid pulls water into its body and then rapidly ejects the water backward to prop
el itself forward. A 1.5 kg squid (not including water mass) can accelerate at 20 m/s2 by ejecting 0.15 kg of water.?

Answer:
The magnitude of the resistive force exerted by the water is newtons.
Explanation:
By First and Second Newton's Law, the resistive force exerted by the water on the cruise ship has the same magnitude of forward thrust, with which it is antiparallel to. The equation of equilibrium for the luxury liner is:
(Eq. 1)
Where:
- Forward trust, measured in newtons.
- Resistive force exerted by the water, measured in newtons.
From (Eq. 1), we get that: ()
The magnitude of the resistive force exerted by the water is newtons.
