Question

n a rocket test facility, aerospace engineers are testing a rocket’s propulsion ability during a short test blast. The engineers measure a 150-kg mass flow of exhaust gas through the engine at an average velocity of 200 m/s. What impulse could be delivered by this rocket?

Answer 1

The impulse delivered by the rocket is 30,000 kg·m/s, calculated by multiplying the mass flow of exhaust gas (150 kg) by the velocity of expulsion (200 m/s).

Step-by-step explanation:

The impulse delivered by the rocket can be calculated by using the relationship Impulse = Mass Flow × Velocity.

Impulse is a measure of the change in momentum of an object, and for a rocket, it equates to the mass of exhaust gases expelled times the velocity at which they are expelled.

Given a 150-kg mass flow of exhaust gas through the engine at an average velocity of 200 m/s, the impulse provided by the rocket is:

Impulse = Mass Flow × Velocity

= 150 kg × 200 m/s

= 30,000 kg·m/
