Another scheme to catch the Roadrunner has failed. A safe falls from rest from the top of a 25.0 m high cliff toward Wile E. Coyote, who is standing at the base. Wile first notices the safe after it has fallen 15.0 m. How long does he have to get out of the way.    Some solutions are using the method of finding the difference of time between 25m and 15m. But some are finding the difference of time between 25m and 10m. Which one is correct?.
