Transcribed Image Text:3. Determine the vector magnitudes and directions for the relative velocities VA/B and VB/A, given these magnitudes and directions for the vectors VA and VB: (a) VA: magnitude 70km/h; direction 30° VB: magnitude 50km/h; direction 125°
(b) VA: magnitude 70km/h; direction 30°
VB: magnitude 50km/h; direction 225°
(c) VA: magnitude 70km/h; direction 30°
VB: magnitude 50km/h; direction 340°
(d) VA: magnitude 70km/h; direction 135°
VB: magnitude 50km/h; direction 60⁰
NOTE: The direction is the angle (degrees) from the positive horizontal axes in an anticlockwise direction.
