Relative to the earth, the sailboat sails north with speed vo = 6 knots (nautical miles per hour) and then sails east at the same speed. The telltale indicates the direction of the wind relative to the boat. Determine the direction and magnitude of the wind's velocity (in knots) relative to the earth.

Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.
