Question

A point object is moving with a speed v in front of an arrangement of two mirrors as shown in the figure. The magnitude of velocity of the image in mirror M 1 with respect to the image in mirror M 2 is, 2 v sin θ, v sin θ, 3 v sin θ, 4 v sin θ

Angle between v I 1 and v I 2 is 2 θ . The magnitudes of these vectors is v . ∴ | v → I 1 − v → I 2 | = v 2 + v 2 − 2 v · v · cos 2 θ = 2 v sin θ
