A car is driven east for a distance of 43 km, then north for 29 km, and then in a direction 29° east of north for 24 km. Determine (a) the magnitude (in km) of the car's total displacement from its starting point and (b) the angle (from east) of the car's total...
Will I be still able to transfer to UIUC school of engineering? I have talked to the Illinois advisor, he said as long as you have 3.0gpa. But would one C derail my chances?
I took calc-based physics 1 last semester, but since it was at a community college, I don't think we went as far as the 4 year universities went. We skipped over simple harmonic motion.
Will this hurt me later on, when I go to mid-level and upper-level physics courses at the 4-year university...
What to expect from my class "Theoretical Physics 1"?
I'm starting my major in physics this fall and I'm taking multivariable calculus, mechanics, E & M, and theoretical physics 1.
I pretty much know what to expect from the other 3.
But I'm going into this class "theoretical physics"...
Alright, I'm on the road to be a physicist! This may be the first step towards my career and I'm looking for some advice. So please share me some advice and motivation. I need all the guidance in this course from experts.

A small cart, circular hoop and a solid cylinder of the same mass (5Kg) are allowed to roll down an incline plane. the length of the plane is 22 meters and the angle of incline is 22 degrees. Find the time it takes for each object to reach the bottom of the incline...
Due to time restraints and the fact that my university won't let me take classes at a two year (But won't offer it during the summer themselves -_-) I need to find an accredited four year+ school that offers Physics 1 online over the summer. I've been looking around but haven't found anything as...
Just took my 2nd physics test of the semester. didn't do so well on the first one, so I'm kind of anxious to see how i did on this one(our professor let's us keep the test and we turn in the scantron sheet). honestly, i have no clue how well i did. i know its a lot to ask, but if anyone wants to...

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.
ok, I am of one of those good universities and going to be a physics/math major. I was taking matter and Interaction 1 ( mechanics course honors for freshman), I was doing well in the course attaining very well low As around 88-90, the point drop is significant as 1 question weighs 25 points and...
I missed a week of school last week, and came back to class to find that we have a naked egg drop project due tomorrow. I need to do the entire thing tonight. Does anyone have any suggestions on how to make a good naked egg drop platform (base the egg is dropped into). the egg will be dropped...
Hooray for long titles...
Anyway, I wasn't quite sure where to post this, sorry if this is in the totally wrong forum.
As you may have gathered from the title, I am attempting to make a physics based game. The primary equation in this game is Newton's gravity equation.
F =...
Hi all! Just registered for this forum, wish I had gone looking for help earlier this semester, this would have been nice.
My physics final is tomorrow, and I've been trying to finish up the practice final (I have my calculus 3 final and several other assignments also due tomorrow), but I...
