I need help with this problem. Table L (feet) 0.5, 1.0, 1.5 T (seconds) 0.78, 1.11, 1.36 T=2 pie L/G squared Solve the formula for G. Not sure how to do this can someone help me please.
yes |dw:1322993285116:dw|
now gm can b easily made subject
no it is not t2 it is T=2*pie L/G squared my computer does not have the squared sign on it.
notationwise x squared is x^2
then i am saying it wrong it is the square root of L/G
i know the formula so thats y my answer is correct|dw:1322993751354:dw|
sqrt(L/G) is good :) \[T=2pi\sqrt{\frac{L}{G}}\]
to under the sqrt part; we have to square; they undo each other
Yes that is the way my problem is written can you help me solve for G using the table I put in on my first post.
using the table? prolly. It might mean that you want the primary root.
\[T=2pi\sqrt{\frac{L}{G}}\] \[\left(T=2pi\sqrt{\frac{L}{G}}\right)^2\] \[T^2=4pi^2\frac{L}{G}\] \[GT^2=4pi^2L\] \[G=\frac{4pi^2L}{T^2}\] \[G=\left(\frac{2pi}{T}\right)^2L\] gotta see if that matches up
or rather, use the values of T and L to find values for G
i did it hours b4 amistre
good, then you can tell me if im on the right track :)
All I want is to solve for G using L(ft) 0.5, 1.0, and 1.5 and T(sec) 0.78, 1.11, and 1.36 can this be done and give me a step by step on how to do it.
It can be done. and I just posted the steps for it.
But you are not sure if you are on the right track. If you are then thank you and I will see if it works out. If not on the right track then I will check some where else for the help. Sorry not trying to be rude but this is not easy for me to understand.
momr, if you have confusion with the steps, I can try to explain them. im pretty confident that I have done it correctly
Thank you I will work it out with your steps replacing the numbers for the letters. Thank you again for being patient with me.
good luck with it :) and dont feel uncomfortable in posting any question you may have.
