In Fig. 4-28, particle A moves along the line y = 30 m with a constant velocity `vecv` of magnitude 3.0m/s and parallel to the x axis. At the instant particle A passes the y axis, particle B leaves the origin with a zero initial speed and a constant acceleration `veca` of magnitude `0.40m//s^(2)`. What angle `theta` between `veca` and the positive direction of the y axis would result in a collision?
