In a visit to the nation's capital, a foreign head of state travels from (−3.0, −4.0) km to (4.0, 7.0) km. She then travels with a displacement of (−5.0, -3.8) km. Calculate the her total displacement over the course of the trip.
ANSWER SHOULD BE IN FORM ( , ).
We are not going to do your homework for you. Posting homework under a series of names is even worse, you are deliberating dumping your work here. We will be happy to critique your thinking/and or work.
Have you considered just adding the displacements above?
displacement= (finalx-initialx, finaly-initialy)
That in itself is not an onerous task.
