Hello everyone. First I would just like to say how thankful I am that there is a forum for physics out here. Also I would like to prematurely thank anyone who is going to help me, it is greatly appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

Well I am in ap physics in high school, so this stuff should be cake for you guys.

So I created a quick drawing of the picture, please excuse it, it was a little rushed. But there is a 100N street light hanging from two cables of equal length (in picture) The cables create a 37 degree angle with the top horizontal line. --What is the tension force of each cable?

Could someone please explain to me how you find this, and does it make it easier because (or is it) an equalibrium system?

My second qestion is if you have a 30kg mass on an inclined plane that is 30 degrees to the horizontal, and a 50kg mass that is 60 degrees to the horizontal. Both masses are released at the same time, which hits the ground first?

And I have one final question (if I havent bugged you enough). If I have a mass tied to a string (pendulum) and it is at the bottom of its swing, how far will it have traveled if the mass is 1cm above the bottom of its swing, if the pendulum mass is .2kg?

Again thank you so so much, and I appreciate any and all help

Chris
