Homework Statement


A horizontal plank (m = 2.0 kg, L = 1.0 m) is pivoted at one end. A spring
(k = 1.0 x 10
3
N/m) is attached at the other end, as shown in the figure. Find the angular frequency
(in rad/s) for small oscillations


Homework Equations



w = (mgd/I)^0.5 I= 1/3 ML^2

The Attempt at a Solution


w = (2*9.8*1/ (2/3)

I'm not sure what you did here. Start by writing the force equation and comparing it to that for a simple mass on a spring.
