#"please have a look at the animation"#
#"The position of image "O'(0.5,-0.87)#
#"the velocity of image and object are symmetric with respect to"# #"the mirror."#

Explanation:

enter image source here

#"a )image position is "color(red)(O'(x,y))#

#OO'=1#

#O'_x=1*sin 30^o=1*0.5=0.5#

#O'_y=-1*cos 30^o=-1*0.87=-0.87#

#O'(0.5,-0.87)#

#b)" velocity of image "#

enter image source here

#"the velocity of image and object are symmetric with respect to"# #"the mirror."#
#u=1 m/s" , "v=1m/s "(directions are different)"#
