Perfect! The magnitude of both vectors is $$100 \, \mathrm{km/h}$$. The directions are different because the Mercedes is going towards the East whereas the Rolls-Royce is going towards the West.
Two vectors A and B are equal. What does this imply?
• They can have the same direction, but, different magnitudes
• They can have the same magnitude, but, different directions
• They can have different directions and different magnitudes
• They must have the same direction and the same magnitude
