A rock falls from the top of a mountain and it's speed is 70.56m/s and the acceleration of gravity is 9.8m/s^2. How can I find the height of the mountain?

Bizarre question. Most mountains are broader at the base than at the top. Seems like a falling stone would bounce a lot on the way down.
For the question to be workable you need to assume it falls from a cliff that is the height of the mountain. Also ignore air resistance. And that 70.56m/s must be the final velocity of the rock just before hitting the valley floor.
Then use
Vf^2 = Vo^2 + 2*g*y

i became acrophobic (feared heights) yet misplaced that some years in the past on a curler coaster. approximately midway up the commencing climb the experience close down and the experience team had to stroll us all down a stairway from approximately one hundred ft interior the air. on account that i became hired via yet another topic park for the time of city, and liked curler coasters, I asked the experience attendants some million questions with regards to the experience and the way it labored, and have been given specifically solid solutions. I forgot approximately how intense we've been and have not feared heights on account that. and that i rode that coaster back an analogous day. spectacular experience!

Check FAA records for the highest CFIT involving that mountain and add a little bit to it.
