Question

a boy walks towards a mirror at a speed of 2.5m/s.At what speed his image approaching him?​

Answer 1

Answer:

v=2.5 m/s

-v=-2.5 m/s

Velocity of image w.r.t boy = velocity of object - velocity of image

velocity w.r.t to boy = v - (-v)

=2.5 - (-2.5)

The image velocity is 5 m/s towards the boy.
