Between 2 seconds and 2.5 seconds, the rock hits the ground after it is dropped.
What are distance and time?
When an object is traveling it moves a length known as distance in a specific time, which when divided gives us the speed of the same, distance is measured from a specific point so that we know if the object has changed its direction or not.
The solution to the problem
As you can see at 2s the height of the rock is 0.4m and at 2.5s it is -10.6m, which tells us that in between these values the height would have been 0m, as the movement of the rock is uniform in direction and hence, the rock will hit the ground between 2s and 2.5s.
The rock hits the ground between 2 seconds and 2.5 seconds after it is dropped.
