# Will see the same speed for the ball always?

We have two people. A person(A) that is stadning and another(B) one who drives his car,so he has some velocitty. Lets say that the person B throw a photon from his car. Lets suppose that photon will hit down and will go up again. So both guys see the same speed.
But If instead of light,he throw a ball then both will see the same speed for the ball always?
