Initial and final Velocity

[Ostronomos]

Initial velocity is the velocity of a moving body at a starting point, Vi.

If we are given the acceleration of a moving body and the time of its final velocity, we can calculate initial velocity: Vi = Vf - at.

If we apply this concept to a broader perspective, can we use it to calculate the rate at which the universe is expanding, assuming its boundary is moving at a certain velocity? If not, what do the actual equations look like?

This assumes a constant acceleration, which is not the case.

You need to do a little calculus.
