Answer:
Both balls struck the ground at the same time
Explanation:
At the moment when both balls fall from the top of the tower, they will reach the ground at the same time, as speed is not a function of mass. All the kinematics equations deduced by Isaac Newton, in his studies show that the velocity of a body in free fall is not in function of its mass.
The only way a body falls faster than another is when one of these bodies has a geometry in which air influences its velocity of fall. For example, when comparing the fall of a steel ball with a feather. But in the same way in modern experiments in vacuum chambers with limited air presence, it has been shown that a ball of steel and a Feather Fall at the same speed. Thus, the mass of a body does not influence its rate of fall.
