VERTICAL CIRCULAR MOTION
FOR CASIO fx-9700
By Daniel Wedge

This program may work on other Casio calculators, but I haven't tried it.

The program calculates the speed of an incoming bullet which hits a
block, gets embedded in it, and flies around in a circle, given the
masses of the bullet and the block and the radius of the block's turning
circle.  Useful for physics problems of this sort, but you'll probably
get a variation for which this program is useless!

The program assumes that acceleration due to gravity is 9.8 m s-2

SYMBOLS USED IN THE CODE:
->   assign key (arrow)
@    display (triangle)
*    multiply
/    divide
^2   square sign (x2)
sqrt square root sign - you will need to enter the brackets as well

      (you can make it smaller by making the text smaller, as long as
      you know what it means)
