Physics

Recall the formula for average speed: . To determine the average speed, we need to find the total distance traveled in 11 seconds.

 

To find the distance traveled from a position-time graph, we consider the absolute - value of the changes in position in each part of the motion.

 

Analyze each part of the motion:

Section AB (0 - 2s):

The object is at rest at m. The distance traveled m since there is no change in position ().

 

Section BC (2 - 4s):

The initial position m and the final position m. The distance traveled m.

 

Section CD (4 – 5.5s):

The object is at rest at m. The distance traveled m since .

 

Section DE (5.5 - 6s):

The initial position m and the final position m. The distance traveled m.

 

Section EF (6 - 8s):

The object is at rest at m. The distance traveled m since
