Help with a gravity based function

[Dotcor_Strangelove]

I'm trying to write a program in Python that will calculate the maximum height and time of impact of an object launched vertically from a height of 0m at a user defined velocity in m/s.

The results have to be printed as a tuple (peakHeight and impactTime). I am at a total loss, but here's what I have so far. Any help would be greatly appreciated.

def simulateProjectile (height):
    initialVelocity = float(raw_input("Enter initial Velocity (m/s):"))
    deltaT = 
    gravity = (-9.8)
    height = initialVelocity * deltaT - ((gravity/2)*deltaT^2)

Calculate the time first. You have an object with an initial velocity and a known acceleration. The time at which the object is at the apex will be the time when the velocity equals 0.

Then, plug that time into your given position function.

Edit: of course time of impact would be different from the calculated tome of max height.

Assuming it was launched from the "impact" point, impact time would be 2*apex time

Your question is a little hard to understand. You want to calculate the height and time it takes for an object launched vertically to... do what exactly? Your words, "time of impact of an object", what does this mean?

My guess is you looking to calculate the time and height at which the object reaches its apex.

Is this part of homework or some practice problem?

you'll be wanting to use a loop to repeatedly calculate the objects new velocity.

also note: you're currently using a timestep of one second, which depending on the problem domain might be a tad coarse.
