Answer:
When the 6th ball is being dropped, the time passed since the balls have been dropped are-
3rd ball: 3 seconds
4th ball: 2 seconds
5th ball: 1 second
Hence the distance through which the balls fell in the time is:
3rd ball: 21gt2=21×9.8×32=44.1m
4th ball: 21gt2=21×9.8×22=19.6m
5th ball: 21gt2=21×9.8×12=4.9m
