Thirty years ago when I applied for a mechanics job that was actually one of the questions on the employment test. That and which way would a ball roll in a wagon going around a corner.
Both questions can really only be answered by assuming something about acceleration. Bad questions!
If I'M the one driving, the ball will be pinned against the back wall when going around a corner.
If my wife is driving, it will be pinned against the back of the front seats.

See, once you make an assumption, you can answer the question.![]()
