If velocity of object is 15 m/s at angle of 45 for plane mirror then what is velocity of image wrt to mirror

Expert Answer
plane mirror gives magnification 1 . Also mirror-to-image distance is same as mirror-to-object distance.
Hence as shown in figure, if object is moving from left to right, then image is moving with respect to mirror
in right-to-left direction with same speed.
Hence as seen from mirror, image is approaching mirror with speed ( 15 cos45 ) m/s = ( 15/√2 ) m/s
