Number 20.
In Fig. 4.12, particle A moves along the line y
= 30 m with a constant velocity v of magnitude 3.0 m/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 a of magnitude 0.40 m/s2. What angle θ between → a
and the positive direction of the y axis would result in a
collision?
