Physics

To find the total displacement of the truck, we can break the motion into three phases: acceleration, constant speed, and final acceleration.

 

Phase 1: Acceleration from Rest

Initial velocity = 0 m/s

Acceleration = 3 m/s²

Time   = 6 s

 

Using the formula for displacement:

 

Phase 2: Constant Speed

First, we need to find the final velocity after the first phase:

 

Now, during the constant speed phase ( = 10s):
