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 retarding force that stops the hammer

Explanation

To solve the problem of calculating the average retarding force that stops the hammer, we can follow these steps:

### Step 1: Identify the given values
- Mass of the hammer (m) = 1 kg
- Initial speed (u) = 6 m/s
- Final speed (v) = 0 m/s (since it comes to rest)
- Time taken (t) = 0.1 s
