how do i do this and what does it mean by expressing as a function?

You are visiting New York City and are allowed to travel to the top of the Empire State Building. You're curious to know how tall the building is and, rather than research the height of the building, you decide to put your Algebra 2 skills to good use and calculate the height of the building by experimenting. You spit over the edge of the railing (by letting the spit dangle and drop, thus imparting no initial velocity) and time how long it takes it to reach the ground. If it takes 8 1/8 seconds to land, how tall was the building?

This is a different type of problem. Haven't worked with these in class yet. We were supposed to figure it out over vacation.

A boat in distress launches a flare straight up with a velocity of 190 feet per seconds. Ignoring the height of the boat, how many seconds will it take for the flare to hit the water? What is the maximum height reached by the flare?

I did this so far.

h(t) = v t - 16t^2
h= 190t-16t^2.

I'm not sure where to go from here.
