Amateur velocity/speed question

Good evening,
I wonder if anyone can either:

- give a direct answer to my question
- maybe point me in the right direction as to where I should be looking for
the math or answer to my question
- tell me to go away as this is a serious group

The question is:
If I have an object such as an iron ball 3 inches in diameter, wiehging 1
kilogram that is propelled upwards at the speed of light (or close), from a
stationary position with the force of gravity acting against it. How long
should it take to reach it's maximum velocity (close to light speed). I hope
this makes sense.

TIA

Mr Mint

Not as serious as some.

"with mass of 1 kilogram"

You would have to assume something about the source of the gravity.

It starts out with its maximum velocity, and this decreases as it climbs
out of the "potential well".

Thank you David, you have helped me to ask the question I was trying to form
originally.

Would you know a formula or where I should be looking to find out more
information about an accelerating objects' starting speed and its final
speed over a given distance.

As long as you stay far away from c, you can always use Newton:
the relationship between velocity and acceleration
v=a * t + v0
the relationship between distance, velocity, and acceleration
s=1/2 * a * t^2 + v0 * t +s0

Since you have established that you are only interested in a differential
measurement, s0 can be zero.

If you want to work closer to c, you'll need to look at energies... a much
more complicated process. Especially when you consider that the moving
observer, and the stationary observer will not agree on the rate of speed.
