5. Squids have built in propulsion systems. A squid draws water into its mantle
cavity and propels itself forward by forcing the water out through a tube called a
siphon. A scientist studying an 8.0 kg squid observes that the squid draws in 0.60
kg of water and then ejects the water in 0.15 seconds at a velocity of 15.0 m/s.
What is the average force on the squid during the propulsion?
A 45 N
B 60 N
C 90 N
D 800 N
