In a 3D coordinate system a plane mirror is placed parallel to XY plane and above the mirror a point object is moving at velocity `vecv_(0)=5hati-3hatj-1lhatkm//s` If mirror is also moving parallel to it self at velocity `vecv_(m)=2hati+hatj-3hatk,` find the velocity of image produced in mirror,
`[5hati-3hatj+5hatkm//s]`
