Settle an argument please !! Look at the picture. The van is travelling forwards at 100mph. A motorcycle is ridden forwards out the van, off a ramp at 20mph. 1) what direction will the bike front wheel be travelling as it leaves the ramp. 2) What direction will the whole bike be travelling as it rolls of the ramp 3) What direction will the bike be travelling at when both wheels exit the ramp. I believe the front wheel will hit the tarmac, skid to a stop then start travelling in the same direction as the van wheels. As the rear wheel exits the van, it will also skid to a halt and also start turning at at the same direction as the van wheels. The bike then will be travelling in reverse, in the same direction as the van until it comes to a stop, then will start travelling in the opposite as the van under its own power. I think you would have to leave the ramp at more than 100mph to make the bike be travel immediatly in the opposite direction as the van. Others think the bike will travel in the opposite direction as the van as soon as it exits the van if the bike is travelling at 20mph. please ignore the potential to crash etc !!
