Part A-The average acceleration of gravity at the earths surface is A) 9.8 m/s/s because the earth is pushing everything up B) o m/s/s. because we neither go up or down C) -9.8 m/s/s because the earth is pulling us down towards its center Part B- if jumping up gravity is the same only your speed changers.
