Homework Statement
I'm stuck on the last 2 parts of this problem and would really appreciate any help!
A pendulum of length 2m and mass 1kg oscillates about its equilibrium position. At time 1s it has a displacement of 20cm. Assume that (phi symbol) = 0 rad.
Homework Equations
a) Its angular velocity
b) the frequency of oscilation
c) the amplitude
d) the maximum angle from the verticle made by the pendulum
e) the speed of the pendulum is given by v(t) = w(ang. vel)A(amplitude)cos(wt+phi). Calculate the kinetic energy at positions theta = 0 rad and theta = 1/2 pi rad
f) where on the pendulum's cycle do these energies occur and why are they different?
