So I have a multiple step problem for my mechanics class and the teacher decided to write his own solutions. I know exactly how to attempt and finish the problem. I know it will be wrong. Recently if I try things on my own there will be a slight gap in the knowledge or math, or magic physics magic that will lead to be the problem being completely incorrect to my understanding of it. Its getting slightly better the more problems I do, but this one has no solutions so there is about as much chance of my knowing if I solved the problem correctly as there is about detecting gravitational waves with a overcooked scallop.
