| The flight of a rocket has two phases: The 'burn' phase that starts at sea level, at rest and and at constant acceleration, increases altitude until it runs out of fuel and The 'coast' phase where the rocket falls back to earth under the influence of gravity. Let's assume that the duration of the burn phase is 85 sec. and the duration of the coast phase is 298 sec. Determine the rocket's peak altitude in km. Assume perfectly vertical and trajectories a constant acceleration back to earth, 9.81 m/s/s\ |
