Answer:Acceleration due to gravity is 9.8m/s per second. During the next second you are already falling at 9.8m/s and accelerating to 19.6m/s. So you fall another 9.8 meters, plus 4.9 meters to account for the acceleration. During the third second, you fall 19.6 meters plus 4.9 meters to accout yet again for acceleration.
