Vector AB is equal to vector DCFurther explanation

Vector is a quantity that has a magnitude and direction.

A vector in a cartesian coordinate is represented by an arrow in which the slope of the arrow shows the direction of the vector and the length of the arrow shows the magnitude of the vector.

A position vector of a point is a vector drawn from the base point of the coordinates O (0,0) to that point.

The addition of two vectors can be done in the following ways:

$\overrightarrow {AB} + \overrightarrow {BC} = \overrightarrow {AC}$

A negative vector is a vector with the same magnitude but in opposite direction.

$\overrightarrow {AB} = -\overrightarrow {BA}$

Let's tackle the problem!

Two vectors are equal if they have the same magnitude and direction. In the attached picture, it can be clearly seen that the vector AB has the same magnitude and direction with vector DC. Therefore, vector AB is equal to vector DC.

hi there!

out of the two, (b) precision would be more reasonable. however, both a and b could be pretty reasonable.

You need to be more specific. i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time, then constant velocity is a straight line . . i.e. a line that has constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant velocity is a piece of line that lies on the x-axis . . it's value is zero.
