describe the line segment and direction of object based on the graph.
type here

Explanation:

1. For the first segment (0 to 6 seconds): The position stays constant at 4 meters as time increases. A flat line on a position-time graph means the object is not moving, so speed is 0, and there is no direction of motion.
2. For the second segment (6 to 10 seconds): The position decreases from 4 meters to 0 meters as time increases. A downward-sloping line on a position-time graph means the object moves toward the starting point (or origin) at a constant speed (since the slope is constant).

Answer:

First segment (0-6s): Object is stationary (speed = 0 m/s, no direction of motion).
Second segment (6-10s): Object moves toward the origin at a constant speed of 1 m/s (direction: decreasing position, toward 0 meters).
