An enemy ship is on the east side of a mountain island
as shown in figure p4.89. the enemy ship has maneuvered to within 2 500 m of the 1 800-m-high mountain
peak and can shoot projectiles with an initial speed of
250 m/s. if the western shoreline is horizontally 300 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?
