I'm not going to do your homework buddy
Its called help? You know, showing the steps so I can figure out others? Don't hurt yourself, I know its a hard topic to grasp.
Sarcastic attitudes aren't how you ask for help. Also, I'm not in physics class. I don't claim to know this stuff. Maybe you should pay better attention in class and you would know how to do it yourself instead of having to asking for answers.
Being a douchebag doesn't help either. Since you are unable to help, you should have just passed over this topic.
I was trying to say you should work on figuring it out yourself, it will help you understand it better if you can solve it on your own. You didn't have to cop a stuffty attitude.
Somebody telling you the answer isn't going to help you learn how to figure it out for yourself.
