A projectile with a muzzle velocity of 550 m/s is fired from a gun on top a cliff 460 meters above the sea level. If the projectile hits the ocean surface 49.2 seconds after being fired, determine (a) the angle of elevation of the gun, (b) the range, and (c) the highest point attained above the cliff.
