a. The boost rocket, m=12 Mg, generates an altitude dependent thrust of T(y)=By? where B=1.4 and takes off with an initial launch speed of v=0.2 km/s. How fast is the rocket going once it reaches h=412 km? b. A spaceship is tráveling at vi=777 km/s towards a distant star, M=2.1x1032 kg. If it does not fire its rockets, how fast will it be traveling once it is d-400 Mm?
