Consider a body of water moving on Earth's surface with a constant velocity uo along the y (north) direction, as observed from the Earth-fixed frame, at latitude 0 and longitude . We define the Earth-centered inertial frame of reference CX.Y.Zo and the Earth-fixed frame of reference oxyz (Figure 1). We assume that the body is in the northern hemisphere. For simplicity, assume that the body is located at point o.
1. Express u as observed in the Earth-centered inertial frame of reference CX.Y,Z.
2. Express the body acceleration as observed in the Earth-fixed frame of reference oxyz (north).
