A point object is moving with velocity v 0 = 2 i ^ - 3 j ^ + 4 k ^ in front of a moving plane mirror whose normal is along x - axis. The mirror is moving with velocity v m = i ^ - 4 j ^ + 2 k ^ . Find the velocity vector of image.

Question

A point object is moving with velocity v 0 = 2 i ^ - 3 j ^ + 4 k ^ in front of a moving plane mirror whose normal is along x - axis. The mirror is moving with velocity v m = i ^ - 4 j ^ + 2 k ^ . Find the velocity vector of image., - 5 j ^, - 3 j ^ + 4 k ^, - 4 j ^ + 2 k ^, 2 i ^ - 3 j ^ + 2 k ^

Let velocity of image v i = x i ^ + y j ^ + z k ^ Along the normal, i.e., along x-axis. v im = - v om ⇒ x - 1 = - 2 - 1 ⇒ x = 0 Along y and z - axes v i = v 0
