Typical chemical rockets eject exhaust gases at very high speeds. A common standard value used in physics problems is around 4000 m/s, which helps generate sufficient thrust according to Newton’s third law of motion.
A typical rocket uses 10,000 kgs ₋₃ of fuel and ejects the burnt gases at a speed of:
