A bullet of mass 50 is moving with a velocity of 500 m`s^(-1)` . It penetrates 10 cm into a still target and comes to rest Calculate (a) the kinetic energy possessed by the bullel and (b) the average retarding force offered by the target.

Explanation

To solve the problem step by step, we will calculate (a) the kinetic energy possessed by the bullet and (b) the average retarding force offered by the target.

### Step-by-Step Solution

**Given Data:**
- Mass of the bullet (m) = 50 grams = 0.05 kg (conversion from grams to kilograms)
- Initial velocity (u) = 500 m/s
- Final velocity (v) = 0 m/s (the bullet comes to rest)
