Question

read the abstract and then answer the question. gravity and drag both reduce the maximum altitude that a rocket can reach, increasing the cost of rocket flights. this study hypothesizes that rockets with a smoother surface will experience less drag and reach higher altitudes, given the same thrust as rockets with rough surfaces. to test this hypothesis, three identical model rockets were constructed and given finishes with varying degrees of surface smoothness: roughed with 40 - grt sandpaper, unfinished, and glossed. each rocket was outfitted with b5 - 4 motors and flown ten times. flight results support the initial hypothesis, with the roughened - surface rocket reaching the apogee point at the lowest altitude and the glossed - surface rocket reaching it at the highest. in conclusion, the findings suggest that smoother surface finishes can reduce the drag force enough to affect altitude, thereby potentially increasing rocket efficiency and reducing fuel costs. who is the primary audience? academics in the field of engineering high school math students model rocket hobbyists people concerned about the price of gas

Explanation:

The abstract discusses a technical study on rocket design, drag - force reduction, and efficiency improvement. The language and content are at an academic and engineering - focused level, making it most relevant to academics in engineering. High school math students would not be the primary audience as the content is beyond basic math. Model rocket hobbyists may find it interesting but it's more of an academic study than hobby - focused. People concerned about gas prices are not related to this technical rocket - engineering topic.
