[Resolved] Kinematics problem? 1. The problem statement, all variables and given/known data A small ball rolls horizontally off the edge of a tabletop of height h. It strikes the floor a distance x horizontally away from the edge of the table. (a) How long is the ball in the air? (b) What is its speed at the instant it leaves the table? Please give your answer in terms of the given variables and g. 2. Relevant equations I'm not sure, since there's no numbers involved and it just wants symbolic answers. I'd think it'd be one of the standard kinematics formulas, but there's only two knowns, acceleration and displacement. 3. The attempt at a solution I have no idea where to start. There is no initial velocity given, no final velocity given, and no time given (in fact, that's what the question is looking for). So, how can this problem be solved if there are only two knowns? It's not the fact that they're looking for the answers in terms of x,h,g that's bothering me, I'm not sure how to approach this even if there was actual values. Any help is appreciated!
