A lead bullet strikes an iron wall with a velocity of `400 ms^( -1).` If the bullet falls dead and the heat produced is equally shared between bullet and the wall find the rise in temperature of the bullet. Given, specific heat of bullet `= 125.6 J kg ^(-1) K ^(-1).`

Explanation

To solve the problem step by step, we will follow these calculations:

### Step 1: Calculate the Kinetic Energy of the Bullet
The kinetic energy (KE) of the bullet can be calculated using the formula:
\[ KE = \frac{1}{2} mv^2 \]
Assuming the mass \( m \) of the bullet is 1 kg (as the specific heat is given per kg), and the velocity \( v \) is 400 m/s, we have:
