hey dear your answer is here..
part 1
h=100m
u=0
let objects drops x meter
and time is t

part 2
u=25 m/s
distance upwards is 100-x
time is t


now
for part 1
s=ut +(at^2)/2
x=0×t+(10 t^2)/2
x=5t^2...(1)

part 2
s=ut +(at^2)/2
100-x=25t+(10 t^2)/2
100-x=25t+5t^2.....(2)

from 1 put value of x in 2

100-5t^2=25t+5t^2
10t^2+25t-100=0
2t^2+5t-20=0
