Answer:
5 seconds
Step-by-step explanation:
The relationship between "d" and "the ground" is not described. If we assume that "d" is distance above the ground, then the rock will hit the ground when d=0. This gives rise to the quadratic equation ...
-t^2 +4t +5 = 0
-(t -5)(t +1) = 0
t = 5 or t = -1 are solutions. Only the positive solution is useful.
The rock will hit the ground after 5 seconds.
