In a contraption built by a fraternity, a person sits at the center of a swinging platform with mass m = 400kg, and length L = 4m suspended via two identical arms of length H = 3m. Neglecting the mass of the person, neglecting friction, letting the mass of each arm be mA = 150kg, and assuming that the platform is releasd from rest when theta= 180 (degrees), compute the speed of the person as a function theta for 0 <= theta <= 180. In addition, find the speed of the person for theta = 0(degrees).
