Can you please answer this physics question?

Physics particls question? Can somebody please explain not tell me the answer?

• Particle A moves along the line y = 34 m with a constant velocity of magnitude 3 m/s and 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 of magnitude 0.46 m/s2. What angle θ between particle B and the positive direction of the y axis would result in a collision?

• Answer:

  ummmmm.... 4.
