A car accelerates uniformly at 4 m `s^(-2)` from rest. Find its velocity at the end of 5 seconds.

Explanation

To solve the problem of finding the velocity of a car that accelerates uniformly from rest, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the given values:**
- Initial velocity (U) = 0 m/s (since the car starts from rest)
- Acceleration (a) = 4 m/s²
- Time (t) = 5 seconds
