Problem 60PE
How much of a single-stage rocket that is 100,000 kg can be anything but fuel if the rocket is to have a final speed of 8.00 km/s , given that it expels gases at an exhaust velocity of 2.20×103 m/s?
ANSWER:
Solution 60PE
Step 1 of 3
For the given single stage rocket with rest mass , we need to calculate the final mass of the rocket after firing and attaining a final speed of with the exhaust velocity of expels gases at .
Given data,
Rest mass of rocket,
Using
Final velocity of rocket,
Using
Exhaust velocity of expel gases,
To find,
Final mass of rocket after firing,
