another scheme to catch the roadrunner has failed. now a safe, initially at least, falls from the top of a cliff 23.5m above a man while he stands at the cliff's base he notices the safe after it has fallen 14.0m.

1) from rest, how far has the safe fallen when he notices it? (indicate direction)

2)from rest, how far must the safe fall before hitting him?

3)from rest, how long(in second) has the safe fallen when he notices it?

4)from rest, how long(in second) must the safe fall before hitting him?

5)after he first notices the falling safe, how long(in seconds) doest he have to get out of the way?
