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

The main arrows show velocity direction and length represents speed. The short red arrows are acceleration vectors.

Step2: Observe between 1 - 4 seconds

The velocity arrows are getting shorter and acceleration arrows are opposite to velocity direction.

Step3: Determine acceleration and velocity nature

Since acceleration is opposite to velocity, it is negative. And as velocity arrows shorten, object is slowing down and will eventually stop.

Answer:

The object has negative acceleration and eventually stops.
