Are you arguing that 1.12 billion m/s is NOT faster than the speed of light, or are you arguing that the speed required by the kick is not 1.12 billion m/s? Because if it's the former, the speed of light in a vacuum is 300 million m/s (to 3 significant figures), or less than one third of that kick speed. If you're arguing the latter, I don't feel like checking all of the calculations this early in the morning, but you are probably right on that point.

Velocity addition and conservation of momentum don't work like that if the speeds are close to the speed of light.

For further details, please check out special relativity theory.
