document.write( "Question 297057: A soccer ball is kicked from the ground, and its height, h, is given by the function h(t)= -16t^2+80+. How many seconds will it take the soccer ball to hit the ground?
\n" ); document.write( "The \"^2\" means to the 2nd power, just so it wouldn't be confusing.
\n" ); document.write( "And the 16t the \"t\" is the letter. After ^2 the + is a plus and the t after 80 is the letter T.
\n" ); document.write( "

You can put this solution on YOUR website!
h(t)= -16t^2+80t
\n" ); document.write( "should be your equation
\n" ); document.write( "set it to zero
\n" ); document.write( " t=5 and t=0
\n" ); document.write( " it falls back at 5 seconds
\n" ); document.write( "
\n" ); document.write( "
\n" );
