A ball is dropped from a height of 60 meters above the ground. How long does it take to hit the ground?
\n" ); document.write( "--------------------
\n" ); document.write( "s = at^2/2 = 60
\n" ); document.write( "---
\n" ); document.write( "Using 5 m/sec/sec for acceleration,
\n" ); document.write( "5t^2 = 60
\n" ); document.write( "t = sqrt(12) =~ 3.464 seconds
\n" ); document.write( "============
\n" ); document.write( "Some use 4.9 m/sec/sec for acceleration, some use other numbers.
\n" ); document.write( "
\n" );
