The average power of a 1130 kg car accelerating up a 21 m hill, reaching a speed of 18 m/s in 6.5 seconds, is calculated to be 45887.36 watts. The relevant equations used in this calculation are W = Fd for work and P = W/t for power. The discussion emphasizes the importance of clearly presenting calculations, as one participant noted issues with image uploads and suggested typing out the work instead. Overall, the average power calculation is confirmed to be on the lower side, prompting further review of the methodology.
PREREQUISITESStudents studying physics, particularly those focusing on mechanics, as well as educators looking for examples of power calculations in real-world scenarios.

Please be sure the image is clear and easy to read and doesn't upload sideways. Better yet, just type your work into the forum. Probably it only took a few lines of algebra for you to get to your answer. Thanks.Billy Jones said:The methodology used can be seen in the attached picture.
