Challenge: As a befitting reply for arrogance, Admiral Varada is entrusted with launching a projectile from somewhere in the Indian ocean (Latitude angle e South) to the symmetric latitude angle 0 (North) in the same longitudinal plane. What should be the minimum launch velocity of the projectile to accomplish the mission? Neglect Air Drag and rotation of earth. (Radius of earth is R and Mass is M)
