You can use Newton's second equation of motion here.
The first ball has traveled for 6 seconds under gravity with acceleration g and initial velocity=0.
The second ball has traveled for 4 seconds under gravity with acceleration g and initial velocity=0.
Distance between the 2 balls at the end of 6 seconds after the first ball is dropped = 1/2*9.8(36-16)
= 98m
