A block is projected along a rough horizontal road with a speed of 10 m/s. If the coefficient of kinetic friction is 0.10, how far will it travel before coming to rest?

Explanation

To solve the problem of how far a block will travel before coming to rest when projected along a rough horizontal road, we can follow these steps:

### Step 1: Identify the Given Data
- Initial speed of the block, \( u = 10 \, \text{m/s} \)
- Coefficient of kinetic friction, \( \mu = 0.10 \)
- Acceleration due to gravity, \( g = 10 \, \text{m/s}^2 \)

### Step 2: Calculate the Normal Force
