Answer 1

Answer:

When mirror is fixed the speed with which the image moves is equal to 2 times the speed with which the object moves .

So here it will be 4m/s .But image is also moving with 1 m/s speed

So actual speed of image would be 5 m/s with respect to object

Hence relative speed of his image with respect to ground will be 5 -1 =4m/s

HOPE THIS WILL HELP YOU.......

HAVE A GOOD EVENING!!!!
