Question

Exercise 8.62
Obviously, we can make rockets go very fast, but what is areasonable top speed? Assume that a rocket is fired from rest at aspace station in deep space, where gravity isnegligible. Part A If the rocket ejects gas at a relativespeed of 2000 m/s and you want the rocket's speed eventuallyto be 2.00×103 c, where "c" is the speed oflight, what fraction of the initial mass of the rocket and fuel isnot fuel? Part B What is this fraction if the final speed is tobe 3500 m/s? Exercise 8.62
