A class 3 rocket is classified as having an impulse level above 40,960 N-s. Impulse in this context refers to the total change of momentum of the rocket, which is related to the amount of propellant used and the thrust produced over time.

The classification system for rockets is crucial for understanding their capabilities and regulatory requirements. Class 3 rockets are typically more complex and powerful, able to reach higher altitudes and exhibit greater performance characteristics compared to lower class rockets.

The other options outline impulse ranges that do not meet the criteria for class 3 classification. Rockets in the ranges specified by these alternatives would fall into lower classes, signifying different safety and operational considerations. Understanding these classifications helps in aligning a rocket's potential use with appropriate safety measures and regulatory guidelines.
