volume_mute

Suppose a moving object collides with a stationary one and the two stick together.  How will the speed of the stuck-together objects compare to the speed of the original moving object?

Correct Answer

It will be less

Explanation

The momentum of the stuck-together objects must be equal to the momentum of the original moving object.  Since the two objects have a mass greater than the mass of the single object, the speed of the two objects must be less
