Spring Constant Question:URGENT Need Help!
Hi
I am having trouble with this question can someone solve it for me, I have a test tomorrow i really need to get this done.
A person building a seismograph (for detecting earthquakes) needs a heavy mass suspended by a long spring. He constructs the long spring from 8 identical short springs connected together end to end( in series). He attaches one end of this long spring to the roof and hangs a 10.25 kg mass from it. The resonant frequency of this system is exactly 1.26Hz
a) What is the spring constant of this long spring?
b) What is the long spring extension when the mass is attached to it?
c) What is the spring constant of each short spring?
F=-kx
[tex]T=2\pi\sqrt{\frac{m}{k}}[/tex]
a) 642.429
b) not sure
c) i tried to use the [tex]\frac{1}{k_t} = \frac{1}{k_1} + \frac{1}{k_2}[/tex]
P.S
