Problem 15PE

What net external force is exerted on a 1100-kg artillery shell fired from a battleship if the shell is accelerated at 2.40×104 m/s2 ? What is the magnitude of the force exerted on the ship by the artillery shell?

Solution 15PE

Step 1 of 4

An artillery shell of mass is accelerated at when fired from the battleship. Here we need to calculate the net external force that acts on the artillery shell when it is fired with given acceleration. Also, we need to calculate the magnitude of the force that is acted by the artillery shell on the ship. Both of the above forces can be calculated using Newton’s Laws of motion.

Given data,

Mass of artillery shell,

Acceleration of the artillery shell,

To find,

Net external force on artillery shell,

Magnitude of the force acted on the ship,
