Physics

To determine which interval had the greatest acceleration, we need to look at the change rate of the velocity values on the graph.

 

Recall the formula for acceleration from a velocity - time graph:

Acceleration .

 

Analysis of each time interval:

0 - 10 mins:

The initial velocity and the final velocity . The time interval = 10 min.

Acceleration .

 

10 - 15 mins:

The velocity is constant at 60 m/min.

Acceleration .

 

15 - 40 mins:

The initial velocity and the final velocity . The time interval
