Air resistance by launching a 0.5 Kg projectile from a level surface. The projectile was launched with a speed of 30 m/s at a 40 degree angle to the surface. Approximately what horizontal distance does the projectile travel before returning to the elevation from which it was launched? (Note: Assume that the effects of air resistance are negligible.)
