My Teacher gave me an interesting problem in AP Physics which seemed simple at first but has me going insane. The problem was what would happen to the potential energy contained in a spring if 0.2 kg was added to the original 0.2 kg on the spring, which stretched the spring 5 cm. The...

AP PHYSICS PROBLEM...i forgot the formula, someone help me solve! This won't take lon Light of frequency 6.0 x 1014 hz strikes a glass/air boundary at an angle of incidence, ø1. The ray is partially reflected and partially refracted at the boundary as shown. The indices are shown. (a)...

We're doing some coupled motion stuff in my AP Physics class and this is my second year of physics because we didn't do it last year in honors and I'm getting a bit lost with this. Does anyone have any links or explanations to help me understand this a little better?

I'm currently in 11th grade, but decided to get physics ap (physics at the college level) and got the result of my first test (59.2)! =( I am currently using the Cutnell and Johnson Physics Sixth Edition book...i was wondering is there a better book than this and if so what is it? Thanks...

ok I've been trying to figure out this problem for about an hour :/ A golfer drives a ball at an angle of 30 degrees with the horizontal at an initial speed of 60m/sec. How high does the ball rise? ok I am pretty sure this is a projectile problem. Vf=0(?) Vh=52m/s Vv=30m/s (i used sin...

A boy fires a "BB" gun at an angle of 28o above the horizontal. The "BB" strikes a target that is a vertical distance of 1.6 meters above and 12.8 meters to the right of the muzzle (exit point) of the gun. Assuming the bullet has a negative vertical velocity when it strikes the target...

I am doing a sort of independent study of AP physics and I ran across a question that I am pretty sure requires either the law of sines or the law of cosines but I can't remember them, can anyone help me out? Thanks, HT

Hello all I will be taking an AP Computer Science class this year. We will be learning Java. Can anyone give me a quick understanding of Java? What are its uses? Is it similar to C? Thanks

Hello all I was just wondering whether Richard Courant's Differential and Integral Calculus Volumes 1 and 2 would be appropriate for studying AP Calculus AB and BC. Would I be able to learn most of the topics covered in these courses just by using these books? I am asking this, because I do...

Which ones do you recommend? Please give an explanation as well. Thanx

Hey guys. I am not sure where to post this and my knowledge of Physics is very lacking due to very imcompetent teachers at my school, and my lack of motivation to teach myself. That being said, I am going to be a senior in high school and I am planning to take AP Physics B. Problem is...

How did everyone do? :)

Just curious (and nervous bc the test is tomorrow) but is the equation sheet given on the multiple choice section or only on the free response part? Thanks for your help!

Do not talk about the Mulitiple choice exam. DO NOT TALK OR CONVEY OR ALLUDE TO THE MULTIPLE CHOICE PORTION OF THE EXAM AT ALL! Discussions of the Free response is permitted as of Friday or 48hours from 8AM Wednesday 5/5/04 That is not allowed because they recirculate that year after...

Hey everyone... since the AP Physics C Exam is coming up next monday I was looking for old exams online (multiple choice exams) to study from. I've been searching for days and haven't come up with anything. Does anyone know where I can find old multiple choice sections of the AP Physics C Exam.

hello, in lieu of the upcoming ap exam, I have been studying old free response questions from ap exams. I have a question about this one A crash test car of mass 1000kg moving at constant speed of 12m/s collides completely inelastically with an object of mass M at time t=0. the object was...

This is on the sample multiple choice questions in the section in which calculators are permitted. I tried it on my TI-89, and it didn't give an answer...just returned what was input with the integral sign and such... Given that... f'(x) = sin(\frac{\pi \times e^x}{2}) ... and f(0) =...

Heres an AP multiple choice problem that's giving me some trouble: If \frac{\,dy}{\,dt} = ky and k is a nonzero constant, then y could be a) 2e^{kty} b) 2e^{kt} c) e^{kt} +3 d) kty + 5 e) \frac{1}{2}ky^2 + \frac{1}{2} Dont quite know where to begin?

Problem: A particle moves along the x-axis so that any time t >_ 0 its velocity is given by v(t) = ln(t + 1) - 2t + 1. What is the total distance traveled by the particle from t=0 to t=2? Am I correct that the total distance is the area under the curve? I tried doing the integration on my...

To review for the AP Calculus BC test coming up in May, my teacher has been giving us problems from past AP tests to help us review. However, I have absolutely no idea how to do on of the problems that I was assigned: For all real numbers x, f is a differentiable function such that...

[SOLVED] an AP chem free response (please help!) i have a final tomorrow (yea i was procrasinating) and i have to figure out how to do these practice problems! please help you can! i need to know how to do it ASAP! NH3(aq) + H20(l) <---> NH4+(aq) + OH-(aq) In aqueous solution, ammonia...

I'm in standard physics junior year of high school. I really like physics but am wondering if I'll be able to handle AP without pre-calculus (which I'm taking next year also).

A billiard ball has mass M, radius R and moment of inertia about the center of mass Ic=2/5MR^2. The ball is struck by a cue stick along a horiontal line through the ball's center of mass so that the ball initially slides with a velocity Vo. As the ball moves across the table (which has a...

Hi, thank you so much for making this kind of post for students like me. I have tried the quesotins but i want to make sure that i was right. if worng, please correct me. THANK YOU SO MUCH. Also i had attached pictures of the question to give you enough information. PLEASE REFER TO THE PICTURE...

Hi, I need help with my AP Physics questions. I tried all the problems and was unsure of my ways to approach the problems. If you can correct my errors, I would greatly appreciate your help. Thank you! Please answer each question and tell me whether it is right and show me how to do it and...

I am reviewing AP chemical equations in class and we have to figure out the products given the reactants. I don't want to post every single question so could someone explain how to these types of questions in general: potassuium permanganate solution is added to oxalic acid and acidified with...

Hello! My first time on here but having massive troubles with my AP Chemistry homework and need help. I have a question that gives four different reactions and I am asked to calculate the (delta)H for each of them. I am given no more information. I am not sure how to go about the problem...

Should AP Physics questions go under K-12 or college level? I mean we use a college textbook so I am assuming the material matches that of some colleges - but we are still in a high school setting.

I'm going to be a high school senior next year and am planning on majoring in physics at college, unfortuantely our school does not offer an AP Physics course, they only offer one general physics course which I have already taken and which failed to teach me anything. But, since I am majoring in...
