Location Transport

If a car were to drive on to a car transporter on the highway, what speed would it be at when it got on it?

If a car were to drive on to a car transporter on the highway, say the transporter would be doing 70 so the car would be moving a bit faster, what speed would it be at when it got on the transporter?

1. Are you serious? As soon as it gets on the transporter (the back wheels of the car are on it), it goes to 0 because it stops. Otherwise, it could hit the transporter's cab.
2. Relative to the transporter? Only what the difference in speed was between them in the first place.
3. well that's not necessarily true, you may be driving an Aston Martin or a Koeninesegeegezeegeneegen and you may have your foot welded to the floor, and hell you aren't going to be traveling at 0mph. Put it this way, if you wish to conduct this... experiment. Do it. But also get someone to film it and post it on YouTube, it will either be a spectacular grand finale or a big big wreck on a highway.. for once not caused by a Nissan or a woman. good luck with it.
4. I assume it would be going the same speed as you were driving. Only problem is you would be going from a moving platform (road) to a stationary platform (transporter) once you hit the transporter you would fly head first into the back of the rig pulling it. Remeber, the TRANSPORTER is not moving like a treadmill. If it were you would stay in the same spot...assuming same speeds for each.
5. Basic physics question. Assume that the transporter is designed so it's even physically possible for the car to do this without crashing. Then, if it would take a speed of 5 mph to drive onto the transporter when it's stopped, the car would need to be going 75 mph when it wento onto the 70 mph transporter. It would then reach a steady-state speed of 70 mph as it stopped on the transporter.
6. If it was possible for the car to drive onto the transporter, the initial difference in speed would be small. However, the car would have its engine running at a high rpm and wheels turning fast enough to go over 70 mph when it leaves the road. The car would start to move much faster than the transporter, relative to the road. It would be advisable for the car driver to very quickly apply the brakes. The uphill climb and friction would also help to slow the car, but I would predict a huge crash as the car loses control on the transporter.
