O233: periods 1,2
	CM #

A 0.800 kg mass is attached to an ideal spring. The system is mounted on an horizontal air track. When set into motion, the oscillatory period is 0.480 s.

(a) Calculate the frequency of the oscillation, f, in Hz.



f=1/T=1/(0.480 s)=2.08 Hz


(b) Calculate the angular frequency, w, in rad/s.



w = 2pf=2p(2.08 Hz)=13.1 rad/s


(c) Calculate the value of the force constant, k, in N/m.



k=mw2=(0.800 kg)(13.1 rad/s)2=137 N/m
