(2) As long as the ball is in free fall, the law is the same. They all dropped 4.9 meters in the first second, and dropped 9.8 meters per second more than the previous second. Then the total * * * falling distance of 8 seconds is the same as the algorithm of the first question. You can get 3 13.6 meters.
