Yeah I got position vector rA and rB from formula r(t)=v*t, where r and v are vectors. They have this form rA=x*t*i + y*t*j where i and j are unit vectors. What do I get from equatting positions, how do I calculate time from that? The correct answer is that they don't collide and minimal...

Homework Statement The first particle A is starting at origin and it has a velocity vector with magnitude 10km/h and moves at an angle of 30 degrees relative to y axis. The second particle B is starting at (0,5) and it has velocity vector with magnitude 8km/h and moves at an agle of 60 degrees...
