A projectile was fired at an angle of 30.0° above the horizontal with an initial speed of 20 m/s. The same projectile was fired a second time with the sane initial speed of 20 m/s but at a different angle such that the height attained by the projectile in the second launch is one half of the horizontal distance covered by the projectile in the first launch. At what angle was the projectile launched second time?
