A motorcycle travels 1000. km west and then travels 500. km west. What is its total displacement?
Sorry for asking, but how does that make sense?
Oh if an aircraft travels 1000 west and then 500 west, they are adding the distance.
Well....it first traveled 1000 km west
And from this point it traveled another 500 km west
So....the total displacement = 1000 + 500 = 1500 km
