TWO BODIES A AND B ARE MOVING WITH VELOCITIES Va AND Vb MAKING AN ANGLE THETA WITH EACH OTHER. DETERMINE THE RELATIVE VELOCITY OF A WITH RESPECT TO B. WHAT WILL BE THE RELATIVE VELOCITY (1.) WHEN THE TWO BODIES MOVE IN SAME DIRECTION, AND (2.) WHEN THE TWO BODIES MOVE IN OPPOSITE DIRECTION?

Explanation:
Two points A and B are moving independently, then
VB/A=VB−VA
above is the figure showing velocity diagram for the vector equation.
Where,
VB/A= Velocity of B with respect to A, ab in the velocity diagram
VB= Velocity of B in global reference, Ob in the velocity diagram
VA= Velocity of A in global reference, Oa in the velocity diagram
VB/A means velocity of `B’ in a reference attached to `A’ and translating with it.
