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

The total displacement is 30 meters South. Displacement is the difference between the initial and final positions of an object, irrespective of the path taken. In this case, the person returns partially to the initial position after moving North by 50 meters.
The total displacement of the dog from the starting point can be calculated by finding the net displacement, which is the difference between the distances moved in each direction. In this case, the net displacement would be 6m north - 4m south, resulting in a total displacement of 2m north.

zero
The answer is 80 because 100-30+10 is 80.
If a person walks 10 meters north and then walks 10 meters south, their total displacement would be zero since they would end up back where they started.
"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 displacement of the jogger can be found by adding up the individual displacements from each segment. The displacement for the first segment is (5 m/s) * (4 minutes) = 20 meters. The displacement for the second segment is (4 m/s) * (3 minutes) = 12 meters. Therefore, the total displacement is 20 meters + 12 meters = 32 meters.
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.
