A bullet of mass m is fired with muzzle speed vo horizontally and due north from a position at colatitude 8. A. Find the direction and magnitude of the Coriolis force in terms of m, vo, 8, and the earth's angular velocity Q. B. How does the Coriolis force compare with the bullet's weight if vo = 1000 m/s and 0 = 40 deg?
