An enemy ship is on the western side of a mountain island. The enemy ship can maneuver to within 2500 m of the 1800 m high mountain peak and can shoot projectiles with an initial speed of 250 m/s. If the eastern shoreline is horizontally 300 from the peak. What are the distances from the eastern shore at which a ship can be safe from the bombardment of the emeny ship.
Find the highest elevation ƟH that will clear the mountain peak; this will yield the range of the closest point of bombardment.
Next find the lowest elevation ƟL that will clear the mountain peak, this will yield the maximun range under these conditions if both ƟH and ƟL are > 45°; x= 2500m y = 1800m Vi=250m/s.
