\n" ); document.write( "\"4.9t%5E2+%2B+v%5B0%5Dt=+s\" where S = the distance above ground (the height or altitude), t = time in seconds, and \"v%5B0%5D\" is the initial velocity (zero in this case).
\n" ); document.write( "\"4.9t%5E2+=+2265\" Divide both sides by 4.9
\n" ); document.write( "\"t%5E2+=+462.24489\" Now take the square root of both sides.
\n" ); document.write( "\"highlight%28t+=+21.5%29\"seconds. (Rounded to the nearest tenth)
\n" ); document.write( "
