The height of the diver above the water (in feet) is
\n" ); document.write( " $\"h=+-16%28t-1.5%29%28t%2B1%29\"$ with $\"t\"$ measured in seconds after the diver leaves the board.
\n" ); document.write( "The diver hits the water at the time when $\"h=0\"$
\n" ); document.write( "The equation $\"h=+-16%28t-1.5%29%28t%2B1%29\"$ tells you that $\"h=0\"$ when $\"t-1.5=0\"$ and when $\"t%2B1=0\"$
\n" ); document.write( " $\"t-1.5=0\"$ --> $\"highlight%28t=1.5%29\"$ means that the diver hits the water $\"highlight%281.5%29\"$ seconds after leaving the board.
\n" ); document.write( "
\n" ); document.write( "NOTE:
\n" ); document.write( " $\"t%2B1=0\"$ --> $\"t=-1\"$ does not make sense, because it means 1 second before jumping.
\n" ); document.write( "However, an alien seeing a video showing the diver from the time the diver leaves the board may conclude that the diver was shot out of the water 1 second before the start of the video. \n" ); document.write( "
