Well, you are given the formula for finding the time for the object to fall a distance of s feet.
\n" ); document.write( "You are also given the distance, s, which is just the height of the building from which the object is dropped.
\n" ); document.write( "So all you really need to do is to substitute the given value of s (1400 feet)into the appropriate place in the formula and evaluate it.
\n" ); document.write( "\"t+=+%281%2F4%29sqrt%28s%29\" Substitute s = 1400.
\n" ); document.write( "\"t+=+%281%2F4%29sqrt%281400%29\" Simplify.
\n" ); document.write( "\"t+=+%281%2F4%29%2A10%2Asqrt%2814%29\"
\n" ); document.write( "\"t+=+2.5sqrt%2814%29\"seconds. This is the exact answer.
\n" ); document.write( "\"t+=+2.5%283.74%29\"
\n" ); document.write( "\"t+=+9.35\"seconds, approximately.
\n" ); document.write( "
\n" );
