Physics

To solve this, we will use the principle of conservation of momentum. Since the two objects stick together after the collision, it's a perfectly inelastic collision.

 

The formula for momentum conservation is:

 

Where:

(mass of the first object)

(velocity of the first object)

(mass of the second object)

(velocity of the second object)

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

 

Now, substitute the known values into the equation:
