A projectile is fired vertically from point A with an initial speed of 215 ft/sec. Relative to an observer located at B, at what times (find two times t₁ < t₂) will the line of sight to the projectile make an angle of 23° with the horizontal? Compute the magnitude of the speed of the projectile at each time, and ignore the effect of aerodynamic drag on the projectile.

Calculate the height h when the projectile is at point C.
