Like I said, I do have knowledge of algebra, and although I was never properly taught, we have learned bits and pieces of it in school. With this problem, the answer was provided for us. I was attempting to figure out the steps in order to reach the answer given. So when I did the algebra, I was...

I've actually never had an algebra class. I haven't been properly taught the basics of algebra; it's a skill we are expected to learn over time, I guess. I do know how to do it, though, but I will make mistakes. I'm not perfect. The format asks the poster to write out our attempt at the...

I get what you're saying. I'm not opposed to believing the algebra is wrong. You have to understand that I'm, probably quite obviously, new to physics; I'm a sophomore and was put in AP Physics without having ever taken the class before, and when two different people can show me how they got...

I was unsure of her answer at first so I also doublechecked with another physics teacher in the building. This is not only the answer they both gave me, but it's the one given in our textbooks. I think at this point I'd be better off trusting the answer I'm getting by three different sources.

I actually ended up asking my teacher about this. She guided me through the solution: 16sin32+FTsin23=mg 8.47+FT(0.39)=25(9.8) 8.86FT=245 FT=245/8.86= Roughly 29N, which was the answer I was supposed to get. And this was the same answer I was getting earlier.

I got it now. I guess all I needed to see was that second step of the algebra...I don't know why I wasn't getting it before. Sorry for bothering you with such a silly mistake. Thanks for the help, both of you!

16sin32+FTensin23=w 8.47+FTensin23=245N 8.86FTen=245N /8.86 FTen=27.65N Right?

1. I did use sine...did you mean that the other way around? 2. I added 13.56+0.39. I know this can't be done but I'm asked to show my process of thinking and this is what went through my head. I really can't figure this one out. Edit: I'm sorry, I did use cosine for that vertical...

Sorry in advance if I'm meant to post a new topic for this, I checked and couldn't find a rule on it, but I have another question in relation to the previous one. This time, instead of finding the mass of the object, you're supposed to work backwards to find the tension force. The question: An...

Pretty sure I figured this out. I calculated 16sin70+7.2sin40+16 to get a sum of 35.6, which I divided by 9.8 (gravity) to get an answer of 3.63kg=m. I used trigonometric functions (sine, cosine, tangent) to find my answer. It was easy to figure out once I read through the problem carefully...

Homework Statement An object is hanging from three ropes. The first rope is vertical and has a tension of 16N. The second rope leads to the right and makes an angle of 70 degrees with the ceiling and also has a tension of 16N. The third rope leads to the left and makes an angle of 40 degrees...
