A block of mass ` 2 kg` is given velocity `10 m//s` on a rough horizontal surface of friction coefficent`mu = 0.2`. Find the magnitude and the direction of friction force acting on it. After how much time and at what distance it will stop ?

Explanation

To solve the problem, we will break it down into several steps:

### Step 1: Identify the Given Data
- Mass of the block, \( m = 2 \, \text{kg} \)
- Initial velocity, \( u = 10 \, \text{m/s} \)
- Coefficient of friction, \( \mu = 0.2 \)

### Step 2: Calculate the Normal Force
