Relative Velocity (A relative to B)

11.1803m/s

Magnitude

Direction

v_rel,x: 10 m/s

v_rel,y: -5 m/s

Original Velocities

|v_A|: 10 m/s at 0deg

|v_B|: 5 m/s at 90deg

Relative velocity is how fast A appears to move when observed from B's reference frame.

v_A/B = v_A - v_B

v_actual = v_object + v_medium
