An enemy ship is on the east side of a mountain island, as shown in Figure P4.71. The enemy ship has maneuvered to within d1 = 2983 m of the h = 1612 m high mountain peak and can shoot projectiles with an initial speed of vi = 221 m/s. If the western shoreline is horizontally d2 = 355 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?
