Physics

To solve this, we will use the principle of conservation of momentum. Since the bullet embeds itself into the block, it is a perfectly inelastic collision, meaning the objects stick together after the collision.

 

The formula for momentum conservation is:

 

Where:

(mass of the bullet)

(velocity of the bullet)

(mass of the wooden block)

(initial velocity of the block)

is the final velocity of the combined system after the collision.

 

Now, substitute the known values into the equation:
