What is the equation for resultant velocity?

The equation for resultant velocity is the vector sum of all individual velocities acting on an object. Mathematically, it can be represented as Vr = V1 + V2 + V3 + ..., where Vr is the resultant velocity and V1, V2, V3, etc. are the individual velocities. This equation takes into account both the magnitude and direction of each velocity component to determine the overall resultant velocity of the object.
