A fireworks shell P is launched upward from point A and explodes at its apex at an altitude of 275 ft. Relative to an observer at O, determine the values of r˙ and θ˙ when the shell reaches an altitude y = 205 ft. Neglect aerodynamic drag. Calculate the velocity v0 at launch. Calculate the velocity of the shell when it reaches an altitude of y= 205 f
