Sorry, I have informed myself again about the task and so the angles are corrected. The differences are not very much, the relations are still the same. Also the directions of both trains are given with angles and there is a x and y axis. Excuse me for some cases I just used in some cases google...

I guess I have the solution but I am not sure. I am not more able draw because I went for a time away from home (now in train), so there is no possibility write it down for me.

So I am actually not far from solution?

The triangles in the sketch by the Rachfahnen are not perpendicular, you can not use angular functions like tan?

We are not allowed to add something to circuit. We should just switch resistors. I guess. I can't solve it.

Yes, sorry, now it should work. :)

Homework Statement I'm not sure if the construction of this circuit is correct, so that both lamps, which are the same, shine equally brightly. Otherwise only the resistors are given. If it's wrong, what else would it look like? And why?[/B] Homework Equations I guess the laws of Kirchoff...

Excuse me for the picture. Train number 1 isn't moving parallely to x-axis. So is it right that s_1_y should be 0?

*the different velocities

Thank you so far, I'm not quite sure what it would look like when I print for tan beta. Above that one has two partial speeds, almost one of these simply over the Pythagorean theorem to a set together?

Homework Statement [/B] So here is my question: I asked you about a solution approach/solution for the following task: Two rail paths cross at an angle of 145 °. With a constant speed of 60 km/h, they just drive along their tracks, and each of them repels steam/smoke flags, which, among other...
