Assume that wind, which forced a fluids motion along a north to south path suddenly ceases at latitude 45oN and the only acceleration to continue is due to the Coriolis force.
What is the radius R of the circle at velocity 0.1 m.s-1 and 1 m.s-1?
What is the period of revolution, i.e. the time it takes to complete one full circle in both cases?
