I'll keep it short
Underneath the straight section of track (where the car launches), there is a nother mini track that runs the whole length of the launch tunnel. On this mini track is a PUSHER CAR. The pusher car has a method of attaching itself to the underside of the main coaster car.
The pusher car on the mini track, uses a system of Linear Syncronous Motors to to push and pull itself along the mini track - using electro magnets. It is very much like the people mover at MK, but goes a heck of a lot quicker!! Anyway, the pusher car locks itself onto the main car, and when it receives current to the motors, it flies along, and carries the main coaster car with it. Towards the end of the launch tunnel it lets go of the main car, flinging it up the first inversion.
A few seconds later, the pusher car returns back to the start ready to go again. You can see it return if you watch after a launch. You can also feel it hook onto the underside of the main car when u are sitting there waiting to go.
It uses a heck of a lot of electricity - and power supply to the building was a major issue at design/cosntruction time.
A lot of launched coasters dont use the pusher car system, and the LSM force acts directly on the main car. The unique system RnR uses is one of the reasons it is HIGHLY reliable. Most of the other launched coasters (eg Superman) have extreme reliabiltiy problems.

I believe it is either car no1 or no2. Not 100% sure, but it is certainly very near to the front.
still don't know the difference between LSM and LIM
