Watching Old Faithful erupt, you notice that it takes a time for water to emerge from the base of the geyser and reach its maximum height.

Answer 1

Look. If you're then asked about formulas and stuff equally as vague, I'm just going to drop this here.
If you want to find the initial speed, the formula is V initial (or Vo)= g*t;

Where g is the acceleration due to gravity (9.8m/s), and t is time.

to find height, the formula is 1/2gt^2.
