Two objects travel from point A to B. They start with the same speed. 1. The first object travels without any obstacles from A to B. 2. The second object encounters at the middle of the course a planet without an athmosphere. The planet has a tunnel (don't ask why) through which the object flies. The object has enough escape velocity. The Gravity of the Planet should increase the speed of the object and when the object tries to escape, the speed will decrease. Will both objects reach the finish line at the same moment? The first object travels with constant speed, does the second object ever fall below the speed of the first object?
