An object is dropped off a building that is 144 feet tall. After how many seconds does the object hit the ground? (s = 16t2)
\n" ); document.write( ":
\n" ); document.write( "How long to fall 144 ft at a velocity of 16 ft/sec/sec
\n" ); document.write( ":
\n" ); document.write( "16t^2 = 144
\n" ); document.write( "Simplify, divide both sides by 16
\n" ); document.write( "t^2 = 9
\n" ); document.write( "t = 3 seconds \n" ); document.write( "

\n" );
