The velocity of a car increases from `5 ms^(-1)` to `17ms^(-1)` in a period of 6s. Then , the velocity of the car reduces to `5 ms^(-1)` in a further period of 8s. Calculate the acceleration and retardation of the car.

Explanation

To solve the problem, we need to calculate both the acceleration and the retardation of the car based on the given velocities and time intervals.

### Step 1: Calculate the acceleration
1. **Identify the initial and final velocities**:
- Initial velocity (u) = 5 m/s
- Final velocity (v) = 17 m/s
- Time (t) = 6 s
