A and B move with constant velocities in a plane. In the inertial frame moving with A, which statements are correct?

Select all that apply

• Option A

  A is at rest

• Option B

  B moves with velocity v⃗_B-v⃗_A

• Option C

  Minimum separation is the perpendicular distance from A to B's relative trajectory if the perpendicular foot lies at future time

• Option D

  Changing to A's inertial frame changes the physical minimum separation
