a plane mirror is moving with a velocity of 2i+3j+4k. if normal to the plane is along z axis, what is the velocity of image?

velocity of mirror = (velocity of object + velocity of image)/2 Or velocity of image = 2vm – vo = 2(2i + 3j + 4k) – (k) = 4i + 6j + 8k – k = 4i + 6j + 7k

velocity of mirror = (velocity of object + velocity of image)/2 Or velocity of image = 2vm – vo = 2(2i + 3j + 4k) – (k) = 4i + 6j + 8k – k = 4i + 6j + 7k
