Question

the diagram shows a motion map for a train. 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.

Explanation:

Step1: Analyze motion map

The motion - map has segments of motion and a section with just dots.

Step2: Interpret dots

The dots represent the train's position at equal time intervals. When there are just dots without arrows between them, it means the train is not moving. Since there are 3 dots in the non - moving section, it implies the train stopped for 3 seconds. The other statements cannot be supported as there is no indication of direction as south or north, no value of 75 mph, and no comparison of velocities when moving away or towards the origin.

Answer:

The train stopped for 3 seconds.
