A typical model rocket engine exerts an average force of 5 N on its exhaust gas. How much average thrust force does the gas exert on the engine and rocket?

What does Newton's third law state?

Newton's third law says that for every action there is an opposite and equal reaction. Does that mean that the the average thrust force the gas exerts on the engine and rocket would each be 5 N?

To determine the average thrust force that the gas exerts on the engine and rocket, we need to consider Newton's third law, which states that for every action, there is an equal and opposite reaction.

According to Newton's third law, the force exerted by the exhaust gas on the engine and rocket is equal in magnitude but opposite in direction to the force exerted by the engine on the gas.

Since the engine exerts an average force of 5 N on the exhaust gas, the exhaust gas exerts an equal and opposite average force of 5 N on the engine and rocket.

Therefore, the average thrust force that the gas exerts on the engine and rocket is 5 N.
