A model rocket is launched with an initial upward velocity of 39/ms . The rocket\'s height h (in meters) after t seconds is given by the following. h=39t-5t^2. Find all values of t for which the rocket\'s height is 22 meters. Round your answer(s) to the nearest hundredth. Solution h=39t-5t^2 h = 22 22 = 39 t - 5t^2 5t^2 - 39 t + 22 = 0 Solving t = 0.61 seconds (and) t = 7.19 seconds.
