Question

Two particles move with constant velocities in a plane. From A, B is continuously observed along the same bearing while AB is decreasing. Which statements are correct?

G1 Physics · Accepted Answer

Constant bearing with decreasing range means the relative-motion line passes through the origin. Thus relative position and relative velocity are collinear and a collision occurs.
