This is a 2d problem. If I drop a ball with mass m from a height L over ground. How large is the interval that the ball can possibly be on if m = 1 g and L = 2m. Use the uncertainty principle [tex]\Delta[/tex]x[tex]\Delta[/tex]p ~h to determine the interval. Am I supposed to think of this as a classical mechanics problem and just use the uncertainty principle? I'm not sure what [tex]\Delta[/tex]x or [tex]\Delta[/tex]p would be? Or am I supposed to construct a solution to the Schrodinger equation and work with that?
