hi tim, thanks for the fast reponse once again the only thing i did so far was to draw some drafts of what happens... i was thinking maybe rotating the axis on the R' referential, in a way that the movement of the hole is done along 1 single direction, let's say, the z' axis... but i...

Homework Statement A bar (lo = 10mm) is moving along the x-axis with speed v according to a referential R. Meanwhile a table, parallel to the bar is moving along the z axis, with speed u. There's a circular hole in the table with radius = 5mm. From R perspective the bar has l < 10mm and it...

i just googled this site http://www.programmingtutorials.com its pretty much a bookmark collection of online tutorials for some programming languages, seems enough to get you on the right path regarding learning c++ and java, its going to be easy if you are familiar with object oriented...

hi, thanks a lot for the help with the equations :) got the math right, thanks again for the help

i see, so i used this - before the decay px = initial total momentum on x-axis = 0 py = initial total momentum on y-axis = 0- after the decay px = p1x + p3x p1x = p1 = m.g1.v1 where g1 = 1 / √(1 - (v1^2 / c^2) ) p3x = m.g3.v3x where g3 = 1 / √(1 - (v3^2 / c^2) ) ie, I'm considering the...

any help? /cry

Homework Statement A rocket uses a photon radiation engine. Knowing that from a reference R the initial and final rest masses of the rocket are Mi and Mf show that Mi / Mf = sqrt [ ( c + v ) / ( c - v ) ] and that the rocket was initially resting on R Homework Equations Total...

hello, and thanks for your reply part a so, since there is a charge conservation and all 3 new particles are identical then the new charge of each particle is q = Q/3. part b now, about the angle A, since momentum is conserved, and assuming that, after the decay, the particle 1 has momentum...

Homework Statement Let's consider a radioactive decay according to the attached figure. A particle of initial mass M and charge Q is resting according to a referential R and disintegrates itself on 3 identical particles. As shown in the picture, 2 of the particles have known speeds 4c/5 and...
