## momr1958 3 years ago 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.

1. wasiqss

yes |dw:1322993285116:dw|

2. wasiqss

now gm can b easily made subject

3. wasiqss

sorry g**

4. momr1958

no it is not t2 it is T=2*pie L/G squared my computer does not have the squared sign on it.

5. amistre64

notationwise x squared is x^2

6. momr1958

then i am saying it wrong it is the square root of L/G

7. wasiqss

i know the formula so thats y my answer is correct|dw:1322993751354:dw|

8. amistre64

sqrt(L/G) is good :) $T=2pi\sqrt{\frac{L}{G}}$

9. amistre64

to under the sqrt part; we have to square; they undo each other

10. momr1958

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.

11. amistre64

using the table? prolly. It might mean that you want the primary root.

12. amistre64

$T=2pi\sqrt{\frac{L}{G}}$ $\left(T=2pi\sqrt{\frac{L}{G}}\right)^2$ $T^2=4pi^2\frac{L}{G}$ $GT^2=4pi^2L$ $G=\frac{4pi^2L}{T^2}$ $G=\left(\frac{2pi}{T}\right)^2L$ gotta see if that matches up

13. amistre64

or rather, use the values of T and L to find values for G

14. wasiqss

i did it hours b4 amistre

15. amistre64

good, then you can tell me if im on the right track :)

16. momr1958

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.

17. amistre64

It can be done. and I just posted the steps for it.

18. momr1958

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.

19. amistre64

momr, if you have confusion with the steps, I can try to explain them. im pretty confident that I have done it correctly

20. momr1958

Thank you I will work it out with your steps replacing the numbers for the letters. Thank you again for being patient with me.

21. amistre64

good luck with it :) and dont feel uncomfortable in posting any question you may have.
