Suppose you are climbing in the High Sierra when you suddenly find yourself at the edge of a fog-shrouded cliff. To find the height of this cliff, you drop a rock from the top and 7.00 s later, hear the sound of it hitting the ground at the foot of the cliff.

Part A: Ignoring air resistance, how high is the cliff if the speed of sound is 330 m/s

2. Relevant equations

V(final)= V(initial)- g

y(final) = y (initial) +Vi(t) - .5 g(t^2)

(Vf)^2=(Vi)^2 - 2g (Yf-Yi)

3. The attempt at a solution

330 = Yi + 0(7) - .5 (9.8)(700)^2

I'm really having trouble just getting past the first part. It seems like it should be pretty straight forward but I'm probably over thinking it.
