Answer to Question #70705 in Mechanics | Relativity for Ashley

Question

this answer is incorrect. The algebra got messed up when you went from (g^2)(t^2)/(2gt)= (gt^2)/2
It is (gt)/2.
The tsquared is incorrect there. Messed me up for a good 30 minutes trying to figure out how that was true, I realized it is not true.

Answer 1

I don't really know what did you try to do in this algebra expression. However, the result is not correct. As you wrote before, it must be gt/2. When you dividing t^2 by t, you will get only t and when you dividing g by g, you will get 1, which is traditionally not written in the expressions.
