b) Determine the time at which the rocket reaches its maximum height, and the maximum height in feet.
c) For what time interval will the rocket be more than 773 feet above ground level?
d) After how many seconds will it hit the ground?
a) The function that describes the height of the rocket in terms of t is s(t) =
