An object is thrown upward from the top of a 96-foot building with an initial velocity of 80 per second. The height h of the object after t is given by the quadratic equation h=16t+80t+96\r
\n" ); document.write( "\n" ); document.write( "When will the object hit the ground at when the time is how many seconds?
\n" ); document.write( "======================
\n" ); document.write( "Using your equation, it will never hit the ground.
\n" ); document.write( "Use h(t) = -16t^2 + 80t + 96
\n" ); document.write( "Notice the first term is negative, and it's t^2.
\n" ); document.write( "---------
\n" ); document.write( "Use h(t) = -16t^2 + 80t + 96
\n" ); document.write( "It hits the ground when h(t) = 0
\n" ); document.write( "Use h(t) = -16t^2 + 80t + 96 = 0
\n" ); document.write( "Solve for t
\n" ); document.write( "Ignore the negative value of t.
\n" ); document.write( "
\n" ); document.write( "
\n" );
