In the figure, particle A moves along the line y = 31 m with a constant velocity ý of magnitude 3.0 m/s and directed parallel to the x axis. At the instant particle A passes the y axis, particle B leaves the origin with zero initial speed and constant acceleration a of magnitude 0.42 m/s². What angle 0 between a and the positive direction of the y axis would result in a collision? A Number i Units
