The first couple of minutes of the launch of a space shuttle can be described very roughly as follows: The initial mass is
2×106kg
, the final mass (after 2 minutes) is about
1×106kg
, the average exhaust speed
vex
is about 3000 m/s, and the initial velocity is, of course, zero. If all this were taking place in outer space, with negligible gravity, what would be the shuttle's speed at the end of this stage? What is the thrust during the same period and how does it compare with the initial total weight of the shuttle (on earth)?
