Derive the integral in section 2.
Integrate equation 10.3.2 to obtain equation 10.3.3
Integrate equation 10.3.3 to obtain equation 10.3.5
Obtain equation 10.3.6
In the following problems, (numbers 5 - 8) assume:
V = 2 km s-1.
m0 = 2000 kg
b = 0.5 kg s-1
f = 90%
What is the maximum speed, and how long does it take to attain it?
How long does it take to reach a speed of 3 km s-1?
How long does it take for the rocket to travel 600 km?
How fast is it moving when it has travelled 300 km?
