\"h%28t%29+=+-16t%5E2%2Bv%5B0%5Dt%2Bh%5B0%5D\" Initial velocity, \"v%5B0%5D+=+0\" and initial height, \"h%5B0%5D+=+400\"ft.
\n" ); document.write( "When the camera hits the water, h = 0, so...
\n" ); document.write( "\"-16t%5E2%2B400+=+0\"
\n" ); document.write( "\"16t%5E2+=+400\" Divide by 16.
\n" ); document.write( "\"t%5E2+=+25\" Take the square root.
\n" ); document.write( "\"t+=+5\"seconds, neglecting the time it takes for the sound of the splash to travel the 400 feet to Susan's ears.
\n" ); document.write( "
\n" );
