Please help, if a 60(adsbygoogle = window.adsbygoogle || []).push({}); gbob at the end of a cord (unknown length) of negligable mass and the angle [tex]\Theta = (0.0800 radian) cos[(4.43 radian / s.) t + \phi][/tex] <---- Angle between cord and the vertical.

What are

a) the pendulum's length?

b) it's maximum kinetic energy?

Please help, the prof did not go overanyof this type of problem.
