The statement "At the bottom of the hill the skater ALWAYS maintains a speed over 9.8 m/s" is False.
While a skater may attain speeds greater than 9.8 m/s as they descend a hill due to gravitational acceleration, it is not guaranteed that they will always do so, as their speed will depend on factors such as their initial speed, the height of the hill, friction, air resistance, and other forces acting on the skater.
