25 m/s for 140 sDistance = Rate X Timeso..........due west displacement = 3500 meters ( call this a )due south displacement = 1005 meters ( call this b )you are looking for the hypotenuse of a triangle and your direction will be south westerlya^2 + b^2 = c^2 ( you want c )c = sqrt(a^2 + b^2)= 3641.43 meters as magnitudeDirection of displacement from start point is arctan (1005 / 3500) = 16.021 degrees.For interest the true compass direction from start point will be 270 - 16.021 = 253.98 degrees (true) on a chart. Compass degrees measure clockwise, starting at North is 0°
If you have moved forward and backward, hence ending up at the same point you started, then displacement is zero. That's because Displacement takes into account the direction - hence a vector quantity.The distance only bothers about the distance - hence it doesn't matter if you came to where you started. So in total, 5 meters up and 5 down is 10. Distance = 10

Total displacement is 2 meters.

The answer is 80 because 100-30+10 is 80.
Displacement is basically the total space between point A and point B. Commonly mistaken, displacement is different than distance. For example, if somebody walked 5 meters to the right, then 4 meters to the left, their displacement would be 1 meter, and their distance walked would be 9 meters.
"Displacement" in physics usually referrs to the net change in position - meaning, take a snapshot of the dog before he starts moving and a snapshot of the dog when he's finished moving, and the distance between his two positions is his net displacement. Nothing he does in between affects the result - only where he starts and where he ends up.If you walk 6 meters north and then turn around and walk 4 meters south, I hope it makes sense that you are now standing 2 meters north of the point where you started. This is your net displacement (2 meters north).
The total distance traveled (corresponding to the amount of gas the car would burn on such a trip) is 26 meters.The magnitude of the displacement vector = (Dfinal - Dinitial) = 4 meters north.
