Two metal balls are of the same size, but one weighs twice as much as the other. The balls are dropped from the roof of a single-story building at the same time. The time it takes the balls to reach the ground below is:

• about the same for both balls

• about half as long for the heavier ball as for the lighter one

• about half as long for the lighter ball as for the heavier one

• considerably less for the lighter ball but not necessarily half as long
