I agree with you.
But what is the relative velocity between an asteroid of 1000 kg and a bullet of 1000 kg.
I know this forum is not to give answer but to help people.
My answer is: there is no velocity possible. The object fall always back. OR. Never reach the infinite.
Why. Because of the time, the infinite duration. Whish not exist.
Mathematic is a language. It is not physic.
Take an apple. Cut its in a infitive pieces.
What have you? An infinite of small, very small piece of apple.
Put them together. You have a cuted apple.Divide 3 by infiinity. You have nothing. And you don't respect the first low of thermodynamic.
Am i rigth?
Luc B.
No, you are wrong.
If the bullet comes back, then it must come back at some (finite) time. Try to calculate that time and you'll find that there is no such time. Therefore, the bullet never comes back.
There is no need to take about "infinity".
