Find the initial velocity of a car which is stopped in 10 seconds by applying brakes. The retardation due to brakes is 2.5 m/`s^(2)`.

Explanation

To find the initial velocity of a car that stops in 10 seconds with a retardation of 2.5 m/s², we can use the first equation of motion. Here’s a step-by-step solution:

### Step 1: Identify the known values
- Final velocity (V) = 0 m/s (the car comes to a stop)
- Time (t) = 10 seconds
- Retardation (a) = -2.5 m/s² (retardation is negative acceleration)

### Step 2: Use the first equation of motion
