A High Power Rocket is defined by which of the following criteria?

A High Power Rocket is defined by a combination of criteria that align with the specific characteristics of high power rocketry as established by regulatory bodies like the Canadian Association of Rocketry (CAR).

One key criterion is that these rockets have a total impulse greater than 160 Newton-seconds. Total impulse is a measure of the total momentum delivered by the rocket motor over time, and this threshold distinguishes high power rockets from lower power models. The physics of rocketry indicates that higher total impulse allows for larger and more complex flights, often requiring more advanced construction and safety considerations.

Additionally, high power rockets typically weigh more than 1500 grams. This weight threshold ensures that these rockets are robust enough to handle higher stresses and forces encountered during flight, which is necessary given their increased size and performance.

Descent rate control is also important for high power rockets. This feature involves specific design measures such as recovery systems that manage how quickly the rocket returns to the ground after flight. This is crucial for safety, as larger rockets can pose greater risks if they fall uncontrollably.

Thus, all these criteria collectively define a High Power Rocket, making the comprehensive choice that includes every aspect the correct answer. Each criterion not only supports increased flight performance but also promotes safety and adherence
