A) Mountain rescue officers trigger an avalanche by firing a gun ata distant mountain slope. The muzzle velocity of the gun is 190m/s. The gun muzzle is at sea level (y=0). The horizontal andvertical distance from the gun to the slope is 640 m and 240 m,respectively. Find the lowest angle between the barrel of the gunand the horizontal plane.
Round your answer to the nearest tenth of degree.
