College physics Definition and 77 Threads

Hello, I'm in my 30's and haven't been studying algebra, trig, or physics for around 19 years. Well, i just failed my second physics test and I'm pretty bummed out about it. However, I was thinking of taking the same class again next semester, but I'm not sure if i will do any better the second...

1. You are given three vectors of lengths A=65.7, B=38.4, and C=43.7. The angles are theta a=29.1 degree and theta b=57.2 degree, and C points along the negative y-axis. (a) Determine the length of the vector A-B+C. (b) Calculate the angle of this vector 2. (a) Rx = Ax-Bx+Cx Ry = Ay-By+Cy...

University Physics, 12th edition by Young and Freedman

I am using this Serway college physics textbook, and I'm wondering if there are any free printer-friendly notes or study guides on the internet. Thanks for your feedback.

I'm taking a summer college physics course and am very behind. It's completely my fault...I'm taking two classes that only last a month, a history and physics, so it's 7 hours credit in one month. A lot of class time (lab is 3 days/week). I just wasn't used to this compact schedule, partied...

Hello everyone, I made a similar post to this last semester when I went onto take my Introduction to Mechanics (1st semester of College Physics) course and asked for some books that will give me some insight to supplement the first few sections of the Halliday and Resnick (1-15, 8th edition)...

Homework Statement Two charges are separated as shown. Where would you place a -3 microCoulombs (mC) charge such that the net force on this charge is 0? + + 4mC 8mC Distance between charges are 80cm apart...

I am an international student trying for undergraduate studies in US(With physics major). I am trying to find a college with good academic and research programs. However, most of the colleges I see seem to be out of my reach(financially and academically). And I am totally confused now. If...

Right now I am currently in physics 111 and I have to take physics 112 next semester and than after that I am finished with my physics courses. Well, we are using College Physics by Randall D. Knight, Brian Jones, and Stuart Field. In my opinion the book is very lacking, especially in the...

[SOLVED] I'm stuck with college physics My college professor decided he didn't want to teach this chapter on Motion in 2D and 3D so he left us to teach ourselves. My first question is this A stone is catapulted at time t = 0, with an initial velocity of magnitude 19.6 m/s and at an angle of...

Homework Statement A tuning forking vibrates at 512Hz falls from rest and accelerates at 9.80m/s^2. How far below the point of release is the tuning fork when waves of the frequency 485Hz reach the release point? Take the sound of sound in air to be 340m/s. Homework Equations...

Two forces of 200N are acting at a common point. The first force acts due East and the second force is acting 40 degrees North of East. Find the magnitude of the resultant force by cosine law and the direction using sine law.

hello everyone, I just registered on this forum and really hate to start off in this manner (and yes, I butchered my name:redface:). I’m truly sorry for opening up my questions with a story though, if you don’t want to read, I truly understand. I completely love the way math classes are...

Has anyone tried it (by F.Bueche and E.Hecht 10th edition)? How is it?

Hi, i need help with my high school ap physics class. I'm using the college physics fifth edition book. Also are there any guides that can help me with the class with that book as the guideline. thanks

I am looking to buy some more Physics texts to enrich my library. Based on your experience, what do you think is the best Physics text(s) (the one(s) that explains things the clearest)?

Homework Statement This is really not an exact question for homework, but it's kind of related. My teacher is using the book "college physics" by Serway. I'm having a lot of frustration with this book, mainly it doesn't explain things step by step. I don't think intro physics is that hard to...

Hey all. I'm not sure if I'm in the right forum to ask a question like this or not, but I'm wondering if anyone has or knows where I can get the Instructor's Ed. of the College Physics 7th Edition textbook with complete solution sets for all the questions. I'm in a class where we basically...

I recently found out that for a graduate program I want to get into (Physical Therpay) that a sequence in physics is required. This worries me because there is no other subject that I abhor more than mathmatics. I can speak 3 languages fluently, but give me a simple math problem and I want to...

PLEASE HELP ME DO ONE OR ALL OR ANY OF THESE STUDY SHEET PROBLEMS THAT WILL BE ON MY TEST IN FOUR DAYS. I NEED HELP QUICK AND WILL REWARD WITH CASH OR FAVOR... OR GOOD WILL IF YOU ARE A KIND PERSON. IM A GOOD GUY IN BAD STRAITS AND NEED A HELPING HAND. CAN YOU LEND IT? OR CAN I BUY IT? PLEASE...

Need Help With College Physics! alright i have some homework questions i need help with, any help would be greatly appreciated: 1.A 300 g baseball traveling at 30 m/s is struck by a bat in the direction from which it came at 40 m/s. Find the impulse of the force on the baseball. 2.A solid...

What is the best way to prepare for upperlevel undergraduate physics finals?

Could someone please direct me to any good sites with tutorials for physics i have been using the phytsics classroom one, which is excellent, but need something which is more practice questions now Thanks guys :cry: :confused: :eek:

A flywheel has a constant angular deceleration of 2.5 rad/sec^2. I need to ... 1. find the angle through which the flywheel turns as it comes to rest from an angular speed of 117 rad/sec. 2. Find the time required for the flywheel to come to rest. So i used the formula...

Does anyone know of any really good general college physics book? The one I have does not explain things very well, and it does not give detailed ways of solving problems. Thanks.

Hi there! I'm a first year student and found quite interesting the MIT on-line video lectures on electromagnetism. http://ocw.mit.edu/OcwWeb/Physics/8...tures/index.htm In one these lectures given by Dr. Walter Lewin it is explained how all college books and teachers wrogly use...

I just took my first quarter of college physics and it made my head spin! I ended up with a C+ in the class and this is only my 2nd C ever. I'm not a genius so I study a lot and enjoy learning. Now, I really want to learn Physics and know that I need to do a lot more work than I did this...
