SOLUTION: t = 0 seconds. Its height, in meters above sea-level, as a function of time is given by h(t) = -4.9t^2 + 310 t + 178. Assuming that the rocket will splash down into the ocean,

Question 859322: t = 0 seconds. Its height, in meters above sea-level, as a function of time is given by h(t) = -4.9t^2 + 310 t + 178.
