To find the total distance traveled by the car, we can break the motion into three phases: acceleration, constant velocity, and deceleration.

Phase 1: Acceleration

Initial velocity = 0 m/s

Final velocity = 20 m/s

Time = 4 s

Using the formula for acceleration:

Now, calculate the distance during this phase:

Phase 2: Constant Velocity

During this phase, the car travels at a constant speed of 20 m/s for 6 seconds:

Phase 3: Deceleration

Initial velocity = 20 m/s

Final velocity = 0 m/s

Time = 2 s

Calculate the deceleration:
