Which stages are included in the flight of a high-power rocket?

The flight of a high-power rocket can be effectively broken down into specific stages that focus on its propulsion and trajectory. The correct answer identifies these stages as powered flight, un-powered ascent, and descent.

In the context of high-power rocketry, powered flight refers to the phase when the rocket’s engine is actively burning fuel to generate thrust. This is the initial phase where the rocket accelerates and climbs upwards against the force of gravity. Once the fuel is depleted, the rocket enters the un-powered ascent phase, which is characterized by the continued rise of the rocket due to the momentum gained during powered flight. During this stage, the rocket continues to rise until gravitational forces and air resistance eventually slow it down.

After it reaches its peak altitude, the descent stage begins. This phase encompasses the return of the rocket to the ground, which may include a controlled descent for recovery purposes if the rocket is designed to be reusable. Understanding these distinct phases is crucial for analyzing the performance and design of high-power rockets.

Other options may describe different aspects of rocketry but do not accurately capture the specific stages involved in a high-power rocket's flight. The identified stages focus on the critical transitioning of powered propulsion and the subsequent phases of flight, making this response the most comprehensive
