Relative Velocity

Relative velocity in two dimensions is calculated as follows:

1. Identify the velocities of both objects (A and B) with respect to the ground
2. Calculate the velocity of object A relative to B using the vector equation:
   v_AB = v_A - v_B
3. Break down the velocities into x and y components
4. Subtract the x-components and y-components separately
5. Combine the resulting x and y components to get the final relative velocity vector

This concept is useful in various applications, such as navigation and collision avoidance.
