Harmonic Motion-Just need to make sure

[jago-k1]

Homework Statement

A mass of 100 g is hanging from a spring and is set into simple harmonic motion. If the period of the pendulum is 0.993 s, what is the spring constant?

Homework Equations

T=2pi(m/k)1/2

The Attempt at a Solution

I just want to make sure its right before I plug in the answer. Thanks.

T^2 = 2pi *(m/k)

k*T^2 = 2pi * m

k = (2pi*m)/T^2 = .637 N

 

[rl.bhat]

T^2 = 2pi *(m/k)

T^2 = 4(pi)^2*(m/k)

 

[jago-k1]

T^2 = 2pi *(m/k)

T^2 = 4(pi)^2*(m/k)

kk, thanks. :)
