Particle A moves along the line y=30m with a constant velocity vector of magnitude 3/ms and it is parallel to the x axis. Right when particle A passes the y-axis Particle B leaves the origin with 0 initial speed and a constant acceleration magnitude of .4m/s/s. What angle theta (which is angle between the acceleration vector and y axis) would result in a collision, also particle B travels in a linear path as well.
(I believe that is it)
The Attempt at a Solution
My thoughts on this problem are to make (Vocos(theta))t+.5a(cos(theta))t^2=(Vocos(theta))t+.5a(cos(theta))t^2, or their x displacements the same, but then again I think I should take account for the y for Particle B, but I'm not exactly sure how to approach this problem though...
