When I was a teenager, I saw a Candid Camera sequence in which they filmed a person struggling with a suitcase that (unknown to that person) contained a large and rapidly spinning gyroscope. Imagine you are carrying such a suitcase where the gyroscope’s angular velocity is oriented horizontally to your right as you carry it in your right hand. Imagine you try to make a left turn, thus turning the suitcase to the left around a vertical axis. What does the suitcase do?
A. It turns to the left as one would expect. B. It tries to turn instead to the right. C. It tries to rotate around a horizontal axis, with its right face turning upward. D. It tries to rotate around a horizontal axis, with its left face turning upward. E. It tries to rotate around a rightward axis, with its front edge moving up.
