Best ResponseYou've already chosen the best response.1Assuming Earth's gravity, the formula for the flight of the particle is: s(t) = 16t^2 + vt + s = 16t^2 + 144t + 160. This has a maximum when t = b/(2a) = 144/[2(16)] = 144/(32) = 9/2. Therefore, the maximum height is s(9/2) = 16(9/2)^2 + 144(9/2) + 160 = 484 feet. SO ANSWER IS D
