Dear NEEL bhatt
if you will through a stone in upward direction with an acceleration 10 m/sec2 in upword direction then it will keep movinf in upword direction ,and it will never come aback to ground.
but if the direction of acceleration is vertically downward .
then find the time when its velocity become zero
V= U -gt
0 = 10 - 10*t
t =1 sec
ans same time it will take to come back to ground
so total time = 2*1 =2 sec
and for hight
V2 =U2 -2gh
0 = 100 -2*10 h
h =5 m
so total distance H =2*5 =10 m
