What acceleration will all objects experience during their flights through the air (on Earth)?

9.8 m/s/s

Explanation:

As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

the answer is 3.1 his answer is wrong mines is right
