lets clear why the image is approchng the body at double its speed.....
in the diagram earlier the image of the body ws 100 m away frm the body(50 +50)...
but nw the image is only 96 m away frm the body (48 +48)...
tht is it is approchng the body at 100 - 96 = 4 m per second.......
rate if useful........correct if wrong













his image in???
is that plane mirror?
assuming that you meant 2m/s with respect to that mirror.. , he is approaching his image@ 4m/s
