A rocket moving in free space has a speed of 2390 m/s relative to the Earth. Its engines
are turned on, and fuel is ejected in a direction
opposite to the rocket motion at a speed of
3070 m/s relative to the rocket.
What is the speed of the rocket relative to
the Earth once its mass is reduced to one half
its mass before ignition?
Answer in units of m/s.
part 2 of 2
What is the thrust on the rocket if it burns
fuel at the rate of 51.5 kg/s?
Answer in units of N.
