∙ 10y agoThe result is the Hypotenuse of a triangle with sides of 1, and 2. So the answer is the square root of (12 + 22 ) = the square root of 5 = 2.2360 miles.

∙ 7y agoThat would be the vector sum; in this case use Pythagorean theorem as east and north are perpendicular; total displacement is sqrt of 5

How is the velocity of an object different from the speed of an object?
Velocity of a moving body is its rate of DISPLACEMENT with respect to time. But speed is distance traveled per unit time. The difference between speed and velocity is that velocity has a direction. 30mph is a speed. 30mph due north is a velocity. Well not really because 'north' is arbitrary but you get the idea. Displacement is both a distance and direction. 30 miles is a distance. 30 miles to the north is a displacement. A two part quantity like velocity or displacement is called a 'vector quantity'. A one part quantity (speed, distance etc) is called a 'scalar quantity'.
Can displacement be more than distance?
No. Distance can be greater than displacement, but not less. The magnitude of the displacement between two points is also the minimum possible distance of a path between the same points.However, the displacement can be zero if the distance is not if the object's starting point and ending point are the same.
What is difference between distance and displacement?
Distance is a scalar quantity; it only gives you the value.Displacement is a vector quantity; it gives you the value and the direction.Example of distance - point A is 40m from point CExample of displacement - Point A is 40m from Point C, in a western direction.
The difference between speed and velocity is that velocity include?
Speed is a scalar and velocity is a vector. A scalar only has magnitude while a vector has magnitude and direction. Example: If you are traveling north at 65 miles an hour your speed is 65 miles an hour, your velocity is 65 miles an hour north. It gets a little more complicated. Speed = distance (a scalar)/time Velocity = Displacement (vector)/time Example: If you run 5 miles in an hour left and then 5 miles in a hour right your speed is 10 miles/2 hours = 5 miles an hour. However, since you end up in the same exact location as where you started your displacement is zero making your velocity zero as well. Think of it this way; since velocity is a vector it requires a direction if i ended up exactly where I started I have no direction, thus velocity must be zero. One more example to clarify: If you ran 6 miles right and 4 miles left in 2 hours, your speed will be 5 miles an hour (10/2=5) your velocity would be 1 mile an hour to the right, since displacement is 2 miles to the right (6 to right - 4 to left = 2 to right) and the time is 2 hours displacement/time = velocity; 2 to the right/2 = 1 mile to the right per hour.
Relationship between velocity and time?
They are inversely proportional, given that displacement is constant, as the equation shows : v = D/t This is logical. The faster an object moves, the less time it will take to travel a specific distance.
Andrea walked 1 block north and than 2 blocks west how you determine her total displacement?
subtract 1 from 2
What is the displacement of a car if it drives 20miles north and then 3 miles south?
It's 17.0m North. (20N - 3S)
A person walks 3 miles north, turns and walks 2 miles east. Calculate the persons distance traveled and their displacement?
Distance 2+3=5 displacement 2
A radio controlled car rolls 10 miles south then reverses direction and rolls 8 miles north The car has traveled a distance of 18 miles and has a displacement of miles south?
2
Andrea walked 1 block north and then 2 blocks west. How would you determine her total displacement?
Draw a vector from her starting point to her ending point
What is the resultant displacement if Mark walked 2 miles east the 1 mile north?
If you want the distance from the starting point, you can use the Pythagorean Theorem. You can also use your calculator's rectangular --> polar conversion; this will give you not only the distance, but also the angle.
What is the correct displacement for the following vectors 4 km south km north 5 km south and 5 km north?
The displacement is a shortest distance. Here, the displacement will be 1 km. It will be in the North direction.
If the displacement is negative 2 north and represents a positive displacement What is the direction?
south
