The CN tower in Toronto, at 1815 ft., is the world's tallest self-supporting tower (no guy wires).
\n" ); document.write( "write a equation if you were to drop a coin from the top
\n" ); document.write( "The acceleration of gravity 16t^2
\n" ); document.write( "h = -16t^2 + 1815; (t in seconds)
\n" ); document.write( ":
\n" ); document.write( "how long would it take a coin to fall to the ground?
\n" ); document.write( "h=0
\n" ); document.write( "-16t^2 + 1815 = 0
\n" ); document.write( "-16t^2 = -1815
\n" ); document.write( "16t^2 = 1815; mult both sides by -1
\n" ); document.write( "t^2 = 1815/16
\n" ); document.write( "t^2 = 113.4375
\n" ); document.write( "t = \"sqrt%28113.4375%29\"
\n" ); document.write( "t = 10.65 sec to hit the ground
\n" ); document.write( ":
\n" ); document.write( "what would the height of the coin be when time was 2 seconds?
\n" ); document.write( "Find how far it would fall in 2 seconds
\n" ); document.write( "h= 16(2^2)
\n" ); document.write( "h = 64ft
\n" ); document.write( "1815 - 64 = 1751 ft the height after 2 seconds
\n" ); document.write( "
\n" ); document.write( "
\n" );
