#9.8m//s^2#

Explanation:

The acceleration due to gravity at the surface of the Earth is #9.8m//s^2#. All objects, whatever their mass, experience this same acceleration unless there is some other force at work. That is the purpose of the qualifier "falls in a vacuum". They are letting us now that there is no air resistance to act against the acceleration.
