A model rocket is launched with an initial upward velocity of 57 m/s. The rocket's height h (in meters) after t seconds is given by the following.
h = 57t - 5t^2
Find all values of t for which the rocket's height is 29 meters. Round the answer(s) to the nearest HUNDRETHS. (If there is more than one answer, use the "or" button.)
t = ____ Seconds
