Question

A plane mirror is placed at origin parallel to y-axis, facing
the positive x axis An object starts from (2m,0,0)with a velocity
of (2^i + 2^j) m/s The relative velocity of image with respect to
object is along

Jyoti Pant · Accepted Answer

Relative velocity of image w r t object=Velocity of image-Velocity
of object
vIO=vI-vO=(-2i+2j)-(2i+2j)=-4i
Thus, the relative velocity of image with respect to object is
along negative x axis
