Please help me part 2

A fireworks shell P is launched upward from point A and explodes at its apex at an altitude of 265 ft. Relative to an observer at O, determine the values of r and when the shell reaches an altitude y = 175 ft. Neglect aerodynamic drag. Part 1 Calculate the velocity vo at launch. Answer: Vo = 325' 130.61 ft/sec A 265'
