A ball is thrown from an initial height of \( 2 \) meters with an initial upward velocity of \( 20 m / s \) . The ball's height \( h \) (in meters) after \( t \) seconds is given by the following. 

\(h = 2 + 20 t - 5 t ^ { 2 }\)

Find all values of \( t \) for which the ball's height is \( 7 \) meters. Round your answer(s) to the nearest hundredth. (If there is more than one answer, use the "or" button.) 

Answer
