1. The problem statement, all variables and given/known data Obviously, we can make rockets to go very fast, but what is a reasonable top speed? Assume that a rocket is fired from rest at a space station in deep space, where gravity is negligible. If the rocket ejects gas at a relative speed of 1100 and you want the rocket's speed eventually to be 1.00×10−3 c, where c is the speed of light, what fraction of the initial mass of the rocket and fuel is not fuel 2. Relevant equations v=v(ex)ln(m/m0) v1=1100lm(m/m0) 3. The attempt at a solution i think im having trouble finding the final velocity. I did another poblem were the final velocity was 4000 m/s and i got it correct.
