(a) what net external force is exerted on a 1100.0-kg artillery shell fired from a battleship if the shell is accelerated at 2.40 × 10 4 m/s 2 ? (b) what is the magnitude of the force exerted on the ship by the artillery shell, and why?

Explanation:

It is given that,

Mass of the artillery shell, m = 1100 kg

Acceleration of he shell,

(a) The magnitude of force exerted on the shell can be calculated using Newton's second law of motion as :

F = ma

F = 26400000 N

or

(b) The magnitude of the force exerted on the ship by the artillery shell will be same but the direction is opposite as per Newton's third law of motion. i.e
