Expert Answer:

Figure shows the image formation of moving object when mirror is also moving .
Object in front of mirror is moving with speed 10 m/s in a direction that makes angle 37o with horizontal.
 
Let mirror moves with speed V in horizontal direction. Vector diagram of minimum image formation is shown in figure.
 
If size of image is minimum means image is vertical as shown in figure.
 
We see from figure the relation between speed V of mirror and speed of the object is given as
 
V = ( 10 cos37 ) m/s  = [ 10 × 0.8 ] m/s = 8 m/s
