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 |
