Answer:
The stone will be
above the ground in

Step-by-step explanation:
As the stone is thrown vertically upward from ground with speed i.e.,
the initial velocity,
,
the final velocity,
,
acceleration due to gravity,
(upward motion)

To calculate the height at which the stone reached above the ground we can use the below formula:


Now, the time taken by stone to reach
above the ground can be calculated using







Thus, at
the stone will reach
above the ground.
