An Observer Moves Towards a Stationary Plane Mirror at a Speed of 4 m/s
We need to find out the Speed of Image With Respect To Mirror
Let the speed of the observer with respect to mirror be S m/s.
Then speed of image with respect to the mirror will be -S m/s.
So, the speed of image wrt observer will be = S-(-S)
So, the speed of image with respect to observer=2+2=4m/s
An observer moves towards a stationary plane mirror at a speed of 4m/s the speed of image with respect to mirror is 4m/s
