But the yard is not at rest if your point of reference is the metre - damn

I'm still trying to get my head around the car entering the garage at c.
the front of the car collides with the end wall but the rear of the car
reaches the end wall at the same time as it gets the "message" to stop.
Same problem with my tongue going into my cheek I fear.
