What is the idea/principle of utility in utilitarianism?Explain the difference between act and rule utilitarianism. Give an example of each as part of your explanation.*** Remember that copying/pasting from any course materials (other than your own words in the Prep Guide), the internet, or using generative AI like ChatGPT to help “write” or “proofread” or “improve” your answer violates my Academic Integrity policy. Note that generative AI is now incorporated into many popular writing and translating platforms (e.g. Grammarly, Quillbot, Google Translate, DeepL, etc.), so if you’re using those platforms, you’re using generative AI in violation of my policy. USE YOUR OWN WORDS or, if you are unable to do that, properly quote/informally cite them as I discuss in the Academic Integrity section of the Syllabus ***

A spring-loaded dart gun is used to shoot a dart straight up into the air, and the dart reaches a maximum height of 24 meters above its point of release. The same dart is shot up a second time from the same gun, but this time the spring is compressed only half as far (compared to the first shot). How far up does the dart go this time? (Neglect friction and assume the spring is ideal and massless.)
