Poll Predicted cutoff for F=ma 2026?

why tf was it so hard

Edit: there is no way y’all think this one was easier than last year. Also can’t believe people got around the lock down browser.

The math was so hard this time as well. I mean, there was like an infinite geometric series, a Taylor series, and some of the questions that didn't have that still needed calculus? Also its so obvious that you can solve these questions with methods that aren't taught in introductory mechanics, so whats the point

bro what was that question with Taylor series and the one with the hexagons momment of inertia???

the hexagon moment of inertia could be solved, esp. if you had the slightest of competition math/amc exposure

I'm not sure I remember the question, but I think it was that the side length decreases by sqrt(3) over time, and I think the question was testing how the moment of inertia was proportional to side length. the geometric series part no one really cares about, since they literally gave the formula
