Physics

To find out how far the object traveled in the first 3 seconds, we need to calculate the area under the velocity-time graph for that time interval.

 

Breakdown of the motion in the first 3 seconds:

1. From t = 0 to t = 1 s:

The velocity increases linearly from 0 m/s to 8 m/s.

The area of this triangle is

 

2. From t = 1s to t = 3s:

The velocity is a constant 8 m/s.

The area of this rectangle is
