Why? You have no cause being found for such an effect, no matter what the calculation finds out about the time it reaches such height. When are you going to try and find out "what" makes it fall back again at all? You are not doing the "physical science" part at all, you are still doing the math prediction worshipping only. Do you even read the groups name? |
