An enemy ship is on the east side of a mountain island, as shown in the figure. The enemy ship has maneuvered to within  d1 = 2077 m  of the  h = 1940 m  high mountain peak and can shoot projectiles with an initial speed of  vi = 244 m/s.  If the western shoreline is horizontally  d2 = 273 m  from the peak, what are the distances from the western shore at which a ship can be safe from the bombardment of the enemy ship?
