You have a pendulum of mass 'm' on a massless cord length 'r'. You set it into motion and measure the maximum angle the cord makes with vertical as tex2html_wrap_inline36 .

a.
What is the total energy 'E' of the system in terms of ' tex2html_wrap_inline38 ', 'm' and 'r'?
b.
Once you have established 'E', what would the Potential Energy (PE), the Kinetic Energy (KE) and velocity (v) be, given an angle tex2html_wrap_inline40 where tex2html_wrap_inline42 ?
