-16t^2 + 500 = 0
16t^2 = 500
t^2 = 500/16 = 31.25
t = √31.25 = appr 5.59 seconds
I have no idea how to even start this, can someone kinda "point me in the right direction" so to speak.
-Compute the time(t) it will take for a tool to fall to the ground when a worker drops from the top of the building.
-Function:h(t)=-16t^2th0 where t is the time in seconds, h is the height in feet at time t, and h0 is the height of the building
-so if the bulding is 500 feet high, then h0 = 500 and the function would be h(t)=-16t^2 + 500
-when the tool reaches the ground, the height of the tool is zero(0) so the function would be: -16t^2 + 500 = 0
-Solve this quadratic equation for t

If I was graphing this it'll open upwards right?
h(t) = 500 - 16 t^2
opens down (sheds water)
if the ground were not at h=0 the tool would keep falling into negative h. (down a deep hole)
The tool is at its maximum height, h = 500 at the beginning when h = 500 and t = 0
It is also below 500 feet in the imaginary time before t = 0, as if it were thrown up and reached 500 feet at zero speed just as you hit your stopwatch:)

Oh ok, thank you so much!
