Physics

To solve this problem, we can use the principle of conservation of momentum. Since the clay balls stick together after the collision, it is a perfectly inelastic collision.

 

The formula for momentum conservation is:

 

Where:

(mass of the first clay ball)

(velocity of the first clay ball)

(mass of the second clay ball)

(velocity of the second clay ball, since it is stationary)

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

 

Now, substitute the known values into the equation:
