A hammer of mass 1 kg moving with a speed of 6 `ms^(-1)` strikes a wall and comes to rest in 0.1 sec. Calculate
Average retardation of the hammer

Explanation

To solve the problem of calculating the average retardation of the hammer, we will use the formula for acceleration, which is defined as the change in velocity over time. Here are the steps to find the average retardation:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Mass of the hammer (m) = 1 kg (not needed for retardation calculation)
- Initial velocity (u) = 6 m/s (the speed of the hammer before hitting the wall)
- Final velocity (v) = 0 m/s (the hammer comes to rest)
