Between 2 seconds and 2.5 seconds, the rock hits the ground after it is dropped.
What are distance and time?
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.
