Can you solve these physics riddles? ft Simone Giertz - Part 1/3

as far as I remember, objects alike on size, shape and surface hits the ground at the same time whatever is their masses are, so I'd guess they have the same air resistance, because they must have the same veloc... waaait a minute, if F=m.a, the gravity force on the heavier mass should bigger, then, to keep things at balance and they reach the same terminal velocity and hit the ground at the same time the heavier mass must have an higher drag from air resistance, right?
