The velocity of a bullet is reduced from `150 ms^(-1)" to "100 ms^(-1)` while travelling through a wooden plank of thickness 50 min. Find the retardation assuming it to be unifrom.

Explanation

To solve the problem of finding the uniform retardation of a bullet as it travels through a wooden plank, we can use the equations of motion. Here’s a step-by-step solution:

### Step 1: Identify the Given Values
- Initial velocity (U) = 150 m/s
- Final velocity (V) = 100 m/s
- Thickness of the wooden plank (S) = 50 mm = 0.05 m (since 1 mm = 0.001 m)

### Step 2: Use the Equation of Motion
