A disk A with mass m moves on a frictionless horizontal surface. The disk is attached to point O with an elastic cord. The disk follows the trajectory shown between and  The coordinates of A at and are (x1, y1) = (−1.5, 5.0) cm and (x2, y2) = (4.0, −3.0) cm, respectively. If the velocity of A at is parallel to the y axis and has a magnitude v1 = 2.0 m/s, determine v2, the speed of A at , knowing that θ = 35°.
