Hello armyray9

Have a look here for an explanation! (http://theory.uwinnipeg.ca/physics/quant/node6.html)

And the full details on the calculations can be found here on page 3 (http://www.wwnorton.com/COLLEGE/chemistry/gilbert/tutorials/interface.asp?chapter=chapter_03&folder=debroglie)
The calculation there is for a ball of 150 gram at 36 M/sec, but you can adapt these data!
