Hi everyone. Thank you for your help! I ended up working through it with my friend who figured out what to do. I feel annoyed that it took me this long but I'm relieved I can move on to the next question. I appreciate everyone's patience with me! Thank you!
Well I assumed I understood them because when I was following along in my lectures, the stuff the professor was explaining was very straightforward and I was able to understand it.
Okay... in one of the examples, Fnet is just equal to the force parallel to the slope, which as you mentioned, is the case here too. In that case, Fnet is 39.54?? Because... Fparallel is mg*sin(theta), so plug in the values, that's what I get.
If Fnet is 39.54, dividing that by the mass gives...
Well, my next homework problem isn't exactly a nicer distraction, so I'll just try to do this. Picking up where we left off, you guys said that theta is the angle between force and displacement. I looked at 24 again, and I re-wrote the two things as vectors (tip-to-tail, is what I learned), and...
I give up for now haha. I've been working on this problem for about 4 hours and I feel like I'm not getting anywhere so I'm gonna work on something else, but I'll reply back when I can take your guys' response into consideration and try the problem again. Will update soon, thank you all for the...
I guess so. I'm a pure math person so I'm very used to just seeing numbers and doing stuff with them and not relating them to real world application. For instance, you mentioned the forces being in opposite direction, but adding them together being one of my mistakes - when I hear the words "Sum...
I calculated Fnet like we mentioned above, Fx,grav + Fapplied.
I'm learning physics at my university and we're emphasizing on forces and vectors, problem is the homework is through Pearson which does not relate to the lectures/current structure of the course, and I also just suck at physics...
