Let $\"+t+\"$ = elapsed time in seconds
\n" ); document.write( " $\"+-16t%5E2+\"$ ft / sec2 is the term that pulls the ball back to earth
\n" ); document.write( " $\"+30t+\"$ ft/sec is the term for the upward velocity
\n" ); document.write( " $\"+4+\"$ ft is the term for feet above ground
\n" ); document.write( " $\"+h%28t%29+\"$ ft is the time-dependent function
\n" ); document.write( " $\"+h%28t%29+=+-16t%5E2+%2B+30t+%2B+4+\"$
\n" ); document.write( "Here's the plot:
