easy thing to forget!

I believe the answer is by integrating twice: y'' = d2y/dx2 = 0 \int y'' dx = \int 0 dx = A (A is a const) and again: \int A dx = Ax +B (B is a const) Get two constants as it is second order and find the constants using the boundary conditions... Hope that helps

there are no rules dictating size, just teddy bear shaped.

hello all, I recently saw a poster for a competition, the idea is that you get a teddy bear and attach a parachute to it, your bear gets thrown off a tower and the bear which is in the air the longest wins. Obviously i thought that if i researched parachutes on the internet i could find...

thanks all, i think i need to read up a lot orelativity in all forms

i recently read that it was possible to acelerate an electron, using a synchrotron to 3/4 c ! Does this imply that if two electrn beams were to be accelerated in this way that the resultant velocity of a collision would be 3/2 c ? If so what would this b like, i.e. there be lots of mass...
