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
