Answer:
Explanation:
Suppose you are standing on a platform connected to a train station. You appear to be at rest to a third person looking at you from the parking lot.
But what happens if you are observed by someone in the dining car of the train that just passed you?
You appear to be moving. He can prove it because your relative size is getting smaller. How does he know that it is he that is moving and that you are standing still? If he has no idea what's going on with his motion, he also has no idea who is moving.
Answer:
Displacement =
Magnitude of displacement = 13.89 units
Angle of displacement = 30.26°
Explanation:
Mark the co-ordinates of each of the end points of the vectors.
The marked co-ordinates are shown below.
Displacement is the shortest distance between two points. Here, displacement between the starting and end points is the vector .
Displacement vector for a point A from origin O is given as:
Magnitude is given as:
Direction of the vector is given as:
Therefore, displacement vector is:
Magnitude of displacement is given as:
Angle of displacement is:
°
