Homework Help Overview
The discussion revolves around a set of four problems related to Newton's laws of motion. Participants are sharing their attempts and seeking feedback on their reasoning and solutions.
Discussion Character
- Exploratory, Assumption checking, Problem interpretation
Approaches and Questions Raised
- Participants are sharing their attempts at solving the problems, particularly focusing on the second problem. There are questions about the visibility of images containing the problems, and some participants express a desire for input on their solutions.
Discussion Status
Some guidance has been offered regarding the approach to the second problem, suggesting that participants should analyze each mass separately to identify the net forces acting on them. There is an acknowledgment of potential confusion when considering the system of three masses together.
Contextual Notes
Participants are working under the constraints of homework rules, which may limit the amount of detail they can share. There is also a mention of the need to correctly identify the directions of forces acting on the masses.

are these images viewable...it'd be a pain to type out the problems.

You shouldn't be looking at the system of 3 masses together, because it is confusing to identify the "net' force acting, and if by chance you get the right combination of forces, the solution is not in the spirit of Newton's 2nd Law. Instead, look at each mass separately, identify the forces acting on each, and use Newton 2 on each. You're going to have to do this anyway to find the tensions. You'll end up with 3 equations which you can solve for the 3 unknowns, T1, T2, and 'a'. I also note that your forces on mass 3 are not directed in the proper direction, although you seem nonethelseess to have correctly identified the forces acting up the plane.the whizz said:
