Squids use jet propulsion. A squid pulls water into its body and rapidly ejects the water backward to propel itself forward. A 1.5 kg ( not including water mass) squid can accelerate at 20 m/s per s by ejecting 0.15 kg of water.
a. What is magnitude of thrust force on squid
b. what is magnitude of the force on the water being ejected?
c. What acceleration is experienced by the water?

a) 30 N

b) 30 N

c) 200 m/s²

Explanation:

a) The thrust force on the squid is responsible for the acceleration of the mass of the squid

F = ma

m = mass of squid = 1.5 kg

a = 20 m/s²

F = 1.5 × 20 = 30 N

b) The force on the ejected water and the thrust force are equal and opposite, according to Newton's third law of motion, they are action and reaction pairs.

Hence the magnitude of the force on the ejected water = 30 N

c) The acceleration of the ejected water is obtained from the force of the ejected water and the mass of water ejected.

F = ma

m = mass of water ejected = 0.15 kg

F = 30 N

a = (F/m) = (30/0.15) = 200 m/s²

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
