I need you to calculate the total time it will take this ceiling fan to come to a stop, and then explain your calculations. I think the keywords are "rotational kinematics" but I'm way out of my depth here. I'll call this off and post the third act (the answer) when someone gives an answer that's inside a 10% margin, paired with an explanation. The winner gets the keys to my heart.
BTW: Let's get a few guesses in there also. Totally from the gut, informed by experience only. I'm interested to see who gets closer — the analysts or the guessers.
BTW: Don't hesitate to get your students in on this also.
BTW: Yes, I already gave this a try but I was undone by the fact that I gave both the first and third act in advance which led to a lot of handwaving and glossy explanation.
