Looking for readup on parametric projectile equation

Hi,

Im trying to find more information about the following projectile equation:

y = (vi/k)(1-e^-kt))(sin a) + (g/k^2)(1-kt-e^-kt))

I apologize for posting this, but I have been looking high and low for this!

I don't recognize that equation at all. What physical situation is it supposed to be modeling?
