Please click on the top link ^ to see the questions. I have already solved them and turned it in, however i would like to see how others would approach the questions and what mathematical manipulations are widely accepted for solving relativity problems.
Please answers 1-4. and please give a few words of reasoning for your answer Thank you in advance.

The way it works here is that YOU provide your solutions and then you'll get comments and suggestions for alternate ways to solve the problems.

Do them one at a time.

Perhaps you have not read my initial post truly, " i have solved them and turned it in."
This means i don't have it! If I received it back , then i wouldn't be on here asking for others methods of solving. I would already have teacher corrected solutions!
I am not being objective, being solely direct.

Perhaps you have not read our posting rules, which are linked at the top of every page; note especially the section titled "Homework Help Guidelines".

Since you've already solved the problems, you should have no problem recreating your solutions and posting them here.

(How can we give you "other" methods if we don't know the methods you already used?)
