Physics

To determine the time intervals where the object speeds up (increases velocity), we need to look for sections of the graph where the velocity is increasing.

Analysis of each interval:

0 - 1 s: The velocity increases from 0 m/s to 8 m/s. The object is speeding up.

3 - 5 s: The velocity increases from 8 m/s to 12 m/s. The object is speeding up....
