document.write( "skydiving If a skydiver jumps from an airplane at a height of 8256 feet, then for the first five seconds her height above the earth is approximated by the formula h=- 16t^2 + 8256. How many seconds does it take her to reach 8000 feet?
\n" );
document.write( " I am thinking 8000= -16t^2 + 8256 16t^2 =256 t^2=16 t=4
\n" );
document.write( "so it takes 4 seconds to fall 256 feet is this right? My husband says this can't be right because skydivers fall much faster than that. Thanks Dianne \n" );
