Suppose you are riding a bike with a speed of 20 m/s due east relative to a person A who is walking on the ground towards east. If your friend B walking on the ground due west measures your speed as 30 m/s due east. Find the relative velocity between two reference frames A and B :- Velocity of A w.r.t B is 5 m/s towards east 2 Velocity of A w.rit B is 5 m/s towards west Velocity of A w.r.t B is 10 m/s towards east Velocity of A w.r.t B is 10 m/s towards west
