∙ 15y agoTo solve this problem, I must explain the concept of vectors. Vectors merely consist of a magnitude and a direction. For this type of problem, the magnitude is the distance the car travels. Imagine arrows that are pointed in the direction of movement, and the same distance as the car moves. In this case, we will say that north is zero degrees. We know that since the car travels 215 km west, the first displacement is 215 west, and this is easy to visualize exactly where the car is. However, since the 85 km displacement is diagonal, it is more difficult to determine where exactly the vector goes. We must break this into components, in other words, two separate vectors. We must find out how far the car moves in the north-south direction, and how far it moves in an east-west direction. We do this using trigonometry. When we assumed that north is zero degrees, we determine that southwest corresponds to -135 degrees. So the calculations go as follows. For the east-west component, 85cos(-135)=-60.104 km. This means that the displacement from this vector is 60.104 km west. For the north-south component, 85sin(-135)= -60.104 km. This means that the displacement for this vector is 60.104 km south. We then add these two vectors to the 215km west. 215km + 60.104km = 275.104km. This means that the car has traveled a total of 275.104 km west. Since the car didn't travel south initally, we can just say that the car traveled 60.104 km south. To find out the straightline distance that this displacement is from the start, we use the pythagreaon theorem. The west and south displacements make up the legs of a right triangle. By adding the squares of these displacements, then taking the square root of the sum, we get 281.593 km from the start point. To get the angle of this displacement, use the inverse tangent function of the north-south component divided by the east-west component. We get 12.32 degrees. We must add this to the 90 degrees we get from the west component, so in the end, the vector can be defined as 281.593 km, -102.32 degrees. Hope this helps.

∙ 10y agoClick this one: http://tuhsphysics.ttsd.k12.or.us/Tutorial/NewIBPS/PS3_7/PS3_7.htm - this will help you! :) I'm also seeking for the answer of this and I gladly found this link. Good luck with your studies! :)
No, changing the order of displacements in a vector diagram does not affect the magnitude or direction of the resultant displacement. The resultant displacement depends only on the initial and final positions, not the order in which the displacements are added.
In a vector diagram, you can represent the initial and final positions of the object as vectors. The displacement of the object is then calculated as the vector that connects the initial and final positions. By measuring the magnitude and direction of this vector, you can determine the object's displacement.

A vector diagram shows direction as well as magnitude
A visual diagram representing the magnitude of a force in a direction.A vectoris an object that has both a magnitude and a direction. Geometrically, we can picture a vectoras a directed line segment, whose length is the magnitude of thevectorand with an arrow indicating the direction. The direction of the vectoris from its tail to its head
The length of a force arrow in a force diagram does not have a direct correlation to the magnitude of the force. The direction of the arrow indicates the direction of the force, while the relative length compared to other force arrows in the diagram shows the relative strength or magnitude of the forces.
It's called a vector
A force can be represented as a vector quantity, with magnitude and direction. This is typically done using a diagram that includes a labeled arrow pointing in the direction of the force with a specific length to represent the magnitude.
The arrows on a force diagram are called vectors. Vectors represent the magnitude and direction of a force acting on an object. The length of the arrow corresponds to the strength of the force, and the direction of the arrow indicates the direction in which the force is acting.
Forces can be shown in a diagram using arrows. The length and direction of the arrows represent the magnitude and direction of the force, respectively. You can label the arrows with the type of force and its value if known.
A characteristic of a correctly drawn vector diagram is that the direction and magnitude of the vectors are accurately represented using appropriate scales. Additionally, the geometric arrangement of the vectors should follow the rules of vector addition or subtraction, depending on the context of the problem.
The direction of the arrow represents the direction of the force; the length of the arrow is proportional to the magnitude of the force.
