A plane mirror in y-z plane is moving with -2i m/s as(3i+j-4k) m/s. What is the velocity of the image?shown. The object shown now starts moving with2 m/sObjectMirror

Answer»

velocity of image will be increased by twice if mirror is coming close to it by some value

so, when mirror is at rest

Vimage = -3i+j-4k ...... ( j and k will be same )

when mirror is moving

so , Vimage = i(-3-4) +j-4k = -7i+j-4k
