Question

Speed of image when object moves towards the mirror (with velocity v) is 2v (with respect to the object)
Now if the object is stationary and the mirror moves towards him what is the speed of the image with respect to the object?

i say its the same thing again.. 2v.. cause whether the mirror moves or the object moves it shouldn't matter right ? :-/ but the text says its v now.. cause the object is stationary! :-/

Answer 1

Answer 2

it should be 2v. i think i read it somewhere. :O

Answer 3

yea.. you can easily argue saying the mirror is moving with v towards the object.. and the image inside the mirror is moving with v towards the mirror itself.. so its 2v

Answer 4

its with respect to a stationary object no? shouldnt it be v then? i dont really know why but if this could help you.

Answer 5

no no no. wait.

Answer 6

it is 2v.. pt i
