Calculate Rocket Momentum & Thrust: 20,000kg, 600kg/s, 300m/s

Click For Summary
SUMMARY

The discussion focuses on calculating the momentum and thrust of a rocket weighing 20,000 kg that expels gases at a rate of 600 kg/s with a velocity of 300 m/s. Using the formula for momentum (p = mv), the momentum of the exhaust gases is determined to be 180,000 kg·m/s. The thrust applied to the rocket engines is calculated using the formula for thrust (F = ma), resulting in a thrust of 180,000 N.

PREREQUISITES
  • Understanding of basic physics concepts such as momentum and thrust
  • Familiarity with the equations p = mv and F = ma
  • Knowledge of units of measurement in physics (kg, m/s, N)
  • Ability to perform basic algebraic calculations
NEXT STEPS
  • Study the principles of rocket propulsion and thrust generation
  • Learn about the conservation of momentum in closed systems
  • Explore advanced topics in fluid dynamics related to rocket exhaust
  • Investigate the impact of varying exhaust velocities on thrust calculations
USEFUL FOR

Aerospace engineers, physics students, and anyone interested in rocket science and propulsion systems.

A 20 000kg rocket exhausts gases at a constant 600kg per second at 300ms^-1

a) Calculate the momentum of the exhaust gases

b) Deduce the thrust applied to the rocket engines


Any help would be much appreciated

Just use:

p=mv

and a=dv/dt

(and F=ma, of course).
