The diagram shows a motion map for a train. A motion map. The position line is a long black arrow pointing right that is labeled x. Above the line are three dots with a vector pointing away from x that start farther right from x. There are three black dots that are in a vertical column above the point of the third vector. There are two yellow vectors with no black dots pointed toward x starting just above the vertical column of three dots. Which statement is supported by the motion map? The train traveled south and then north. The train moved at a velocity of 75 mph north. The train had a greater velocity when it moved away from the origin. The train stopped for 3 seconds.

Answer:

The Train Stopped For 3 Seconds

Explanation:

Just did quiz on edg its right

According to the question, the train stopped for 3 seconds. So the correct option is D.

What is a motion map?

The one-dimensional plots or graphs are constructed from a position line. It is a horizontal line, along which the position of an object can be indicated, while also indicating its acceleration and velocity.

Arrows are used for marking acceleration and velocity and the direction of these arrows marks the direction of the acceleration or the velocity. The size of the arrow is used to represent the magnitude of the velocity or the acceleration.

Thus, to observe the position, acceleration and velocity of an object in motion, a motion map is used.

Velocity and acceleration vector quantities have magnitude as well as direction. Velocity and acceleration are functions of displacement which is the distance covered in a particular direction. Unlike speed which is a function of distance. Distance just measures the distance covered.

Therefore, according to the question, the correct option is D.
