In the figure, particle A moves along the line y =34.0 m with a constant velocity \(\vec{v}\) of magnitude 2.51 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 \(\vec{a}\) of magnitude 0.480 m/s². What angle \(\theta\) between \(\vec{a}\) and the positive direction of the y axis would result in a collision?
