What is the instantaneous acceleration (both magnitude and direction) due to the coriolis force on an object moving at 160 m s^-1 to the west located at 17 degrees south, 86 degrees west?

Answer 1

The Coriolis acceleration is
2 V w sin L

L is the latitude, V is the speed (m/s) and w is the angular rotation rate of Earth in radisns per second. The direction is perpendicular to the velocity vector.
