The x2 inside the parenthesis makes it not a power series. A power series must have x1 inside the parenthesis.

Can you explain why the rope applies a force onto the pulley in that specific direction? I guess I'm really confused about how rope forces work.

All of the forces are accounted for, except for the forces exerted onto the ground and the forces exerted onto the rope. I assumed that these are irrelevant, but maybe they are actually relevant. I could be missing something though

Hmm ok, thanks for pointing that out! Would you mind explaining what else is missing? Or do you think I should figure this out on my own

Are you assuming that m1 and m3 are touching? I've always assumed that they weren't.

That's what other higher level physics students have told me... but free body diagrams are the only tools I have. Maybe that's why I'm having so much trouble with the problem

I only learned about conservation laws from others who are in higher level physics classes. So far in my class, conservation laws weren't even mentioned yet

Yes, someone has pointed that out to me. Since there is no external force on the system as a whole, the system should have a net acceleration of 0. Since block 2 is moving in the positive x-direction, block 1 should move in the negative x-direction to balance out this force. HOWEVER, we haven't...

Thanks for letting me know about the homework rules Orodruin, I was unaware of those. I am pretty confident that the tension force will cause block 2 to move to the right. As a consequence, block 3 will move downwards, since it is attached to block 2. I found this tension force to be equal to...

Homework Statement Additional instructions: Analyze the motion of the system in an inertial frame of reference fixed to the table on which M1 slides. You can't analyze the system with Newton's Laws in the frame of M1 because M1 will accelerate, and that frame will not be inertial. When you...

Thanks in advance for your help!

Homework Statement Alice and Bob are having a competition to see who can throw a baseball the farthest from the top of a hill which slopes downward uniformly at an angle ϕ. Alice plays softball, and Bob doesn't have a particularly good arm, so he knows that he's probably going to lose...
