Ok, so this is probably a really basic question, and I've got a feeling that my brain is just too 'fuzzy' just now and that all my problem is is simple arithmetic, but here it goes... 1. Determine whether or not the box with vertices at (2,1), (5,1), (5,5), and (2,5) is intersected by the...

Ah, that article was exactly what I needed, thanks for your help :D

This is what I have for the problem, http://img156.imageshack.us/img156/2310/questioncb9.jpg Do I have the right idea of what the collision looks like? And how would I use the momentum conservation here, as in U1 (speed of m before) = V2 (speed of M after)?

1. A sphere of mass m impinges obliquely on a sphere of mass M, which is at rest. The coefficient of restitution between the spheres is e. Show that if m=eM, the directions of motion after impact are at right angles 2. Coefficient of restitution - 3. I really don't think I have a...

Well since your in the UK if your serious about getting into the games industry Abertay University in Dundee has a very good course, Computer Games Technology, it gives you the skills to get into the games industry. Im currently in 2nd year of the course :D. The course, covers a lot more than...

Ok so I take moments about the vertical and horizontal edges. How would I do this? Really stuck here and its the last question I have to do so any help would be really appreciated.

So am i right in thinking that I just find the midpoint between the center of gravity of the triangle and rectangle to get the midpoint of the whole shape? My brain is working slowly today have been doing maths and physics since mid day almost 9 straight hours :(

Hi guys, would really appreciate some help with this question, so far I've only been doing really simple c.o.g questions and I'm lost with this one. A triangle has its vertices at the coordinates (0,0),(0,4) and (6,0). A rectangle has its vertices at the coordinates (0,0),(8,0),(8,-4) and...

Thanx for your help, you both nudged me in the right direction. I finally managed to get it, on the angle I got 50.7 (.6 out but that's probably just rounding) And I got the period. It was easier than I thought I was trying all sorts of weird and wonderful things when I wasn't thinking...

I think i need another nudge (or shove) in the right direction, I'm not entirely sure what you mean. Replace w^2 in T=mLw^2 with LsinA? is this what you mean or am i heading in the entirely wrong direction?

I'm probably being really obtuse but how would I find it if I don't have angle A?

So how can I find the angular velocity without the radius or period?

w is the angular speed of the mass. (3ms) L is the length of string (1m) Heres the digram i drew (not very good with paint) http://img2.freeimagehosting.net/uploads/e1b4cfa5c1.jpg Ho would I use my first 2 equations to form the third one and then solve? I'm not too sure what do do to resolve...

1. The string of a conical pendulum is 1m long. An initial speed of 3m/s causes the bob to describe a horizontal circle. Find the inclination of the string to the vertical and the time of revolution. The answers at the back give 50.1 and 1.6s I'm trying to find the angle that the string makes...
