Question

the diagram shows a motion map. which best describes the motion of the object between 1 and 4 seconds? the object has decreasing acceleration and increasing velocity. the object has positive acceleration and eventually stops. the object has decreasing acceleration and decreasing velocity. the object has negative acceleration and eventually stops.

Explanation:

Step1: Analyze motion - map arrows

In the motion - map, the length of the arrows represents velocity magnitude and the change in arrow length represents acceleration. Between 1 and 4 seconds, the arrows are in the negative direction (opposite to the positive x - axis) and are getting shorter.

Step2: Determine acceleration and velocity

Since the arrows are in the negative direction, the velocity is negative. As the arrows are getting shorter, the magnitude of the velocity is decreasing, which means the object is decelerating (negative acceleration). Eventually, the object stops as the arrows become zero - length.

Answer:

The object has negative acceleration and eventually stops.
