In my AP Physics textbook, a picture of Steel Dragon is shown, along with a caption that says the ride's vertical drop is 95.3 meters long.
Alright, I can understand an ordinary textbook making this mistake, but this is a college-level physics textbook. The authors obviously should know that vertical equals ninety degrees, which Steel Dragon's drop is clearly not. There's even a picture that obviously shows the drop being non-vertical. How the hell do physics professors make this kind of mistake?
