In a contraption built by a fraternity, a person is sitting at the center of a swinging platform with length L = 12 ft that is suspended via two identical arms each of length H = 10 ft. Determine the angle θ and the angular speed of the arms if the person is moving upward and to the left with a speed υp = 25 ft/s at the angle ϕ = 33°.
