a ball is dropped from a cliff that is 256 feet high. The distance S (in feet) that it falls in t seconds is given by the formula S=256-16t^2. How many seconds(to tenths) will it take for the ball to hit the ground?
\n" ); document.write( "----
\n" ); document.write( "When the ball hits the ground \"S\" will be zero.
\n" ); document.write( "---
\n" ); document.write( "Solve:
\n" ); document.write( "256-16t^2 = 0
\n" ); document.write( "16t^2 = 256
\n" ); document.write( "t^2 = 16
\n" ); document.write( "---
\n" ); document.write( "Positive solution:
\n" ); document.write( "t = 4 seconds
