when the sith ball is being dropped ,3rd ball has completed 3sec of its journey, therefore position of 3rd ball is x= 1/2gt² =1/2*9.8*9=44.1m . Similarly we can find position of 4th and 5th ball by taking time as 4and 5 sec respectively.

when 6th ball is dropped

5th ball has completed 1 sec
4th ball 2 seconds
and 3rd ball 3 seconds

for each ball u = 0 and a=g

using second eqn of motion find s for each..
