List Next Result -5.54 5.54 (1 point) A "V' shaped formation of birds forms a symmetric structure in which the distance from the leader to the last birds in the Visr 19m, the distance between t hose trailing birds is D-6m and the angle formed by theV is θ. Suppose that the shape is gradually changing: the trailing birds start apart shrinks at a constant rate dlidt = 0.3mmun while maintaining the same distance from the leader (Assume that the structure is always in the shape of a V as the other birds adjust their positions to stay aligned in the flock.) What is the rate of change of the angle Your score was 1 time.
