 * Purpose: Write a program that asks the user for the number of seconds(1-15) 
 *          that an object falls near the surface of the Earth.  
 *          The program calculates and then outputs the distance the object will
 *          fall in the supplied number of seconds.
 * 
 *          Distance=1/2 * 32 * t * t //where t is seconds of fall.
