carol tosses an apple from a balcony to her friend standing on the ground below. the formula h=-16t squared +72t+40 gives the height, h, og the apple in feet t seconds after being tossed. when will the apple hit the ground?
\n" ); document.write( "----
\n" ); document.write( "h(t) = -16t^2 +72t+40
\n" ); document.write( "The 72t indicates she threw the apple upward at 72 ft/sec.
\n" ); document.write( "--> 5 seconds to impact.
\n" ); document.write( "================
\n" ); document.write( "If you use
\n" ); document.write( "h(t) = -16t^2 -72t + 40 (throwing it downward)
\n" ); document.write( "Then it takes 1/2 second to impact, and hits her friend at 88 ft/sec (60 mi/hr) \n" ); document.write( "

\n" );
