You need to provide numbers like the cliff height. "Some high" won't cut it.
Please turn off your caps lock. It is like being yelled at.
A STONE IS DROPPED FROM A CLIFF SOME HIGH. DISREGARDING AIR RESISTENCE, (a) HOW LONG DOES IT TAKE THE STONE TO REACH THE GROUND? (b) WHAT IS ITS SPEED WHEN IT STRIKE THE AROUND?

I assume you are looking for a general expression for the time it takes an object to fall from a cliff of height "h".
From h = Vot + gt^2/2
where H = the height of the cliff
Vo = the initial velocity = 0
g = acceleration due to gravity and t = the time of the fall.
Solving for t yields
t = sqrt(2h/g).
Choose your "h" and you have the time of the fall.

h=100m t=200/9.8= 20.408 sec.
