Yes it is true because when the net force is 0 then there is no force
Okay assuming the log had no initial vertical motion (you threw it straight out), the distance to the bottom is
dist = 1/2 gt^2 = 1/2 x 9.8m/s/s x
(5.65s)^2 = 156.4m
the velocity at the bottom = g t = 9.m/s/s x 5.65s =55.4m/s
Hope this helps!
