Unformatted text preview: b) How much thrust (force) do the first stage rocket engines generate? c) After the first stage engine cutoff, the first stage is now dry of fuel and is jettisoned using explosive charges. The explosive charges give a rapid impulse to the upper stages, after which they are traveling at 2900 m/s. How fast is the empty first stage traveling after being jettisoned? d) If we neglect frictional air resistance, how much energy is released when the empty first stage hits the ground (or ocean).
