What is the elevator's average acceleration from t = 2 to t= 8? Leave your answer in 3 significant figures.

Average Acceleration = 0 m/s²

Explanation:

The average acceleration between t = 2 sec to t = 8 sec is given as follows:

Average Acceleration = (Final Velocity - Initial Velocity)/Total Time

From Graph,

Total Time = 8 sec - 2 sec = 6 sec

At t = 2 sec

Initial Velocity = 3 m/2 s = 1.5 m/s

At t = 8 sec

Final velocity = 12 m/8 s = 1.5 m/s

Therefore,

Average Acceleration = (1.5 m/s - 1.5 m/s)/ 6 s

Average Acceleration = 0 m/s²
