Physics

To find the final velocity of the truck, we will break the problem into three parts:

1. First acceleration (from rest)

2. Constant speed travel

3. Second acceleration

 

Part 1: First Acceleration

Initial velocity = 0 m/s (starting from rest)

Acceleration = 3 m/s²

Time = 6 s

 

Final velocity after the first acceleration:

 

Part 2: Constant Speed Travel

The truck travels at a constant speed of 18 m/s for 10 seconds. The velocity remains:
