Determine the frequency and period for a pendulum of length 250cm, mass of 500g, and amplitude of 25cm
I don't understand how to do this, help would be appreciated! Thank you

use sci units
L = 2.50 meters
m = 0.5 kg
g on earth is about 9.81 m/s^2
amplitude of .25 is irrelevant to usual approximation but see http://en.wikipedia.org/wiki/Pendulum
ignoring amplitude:
T = period = 2 pi sqrt (L/g)
T = 2(3.14)sqrt (2.5/9.81) seconds
frequency = 1/T Hz
