Question

The rear view mirror of a car is a plane mirror. A driver is reversing his car

at a speed of 3 m/s. The driver sees in his rear view mirror the Image of a

truck parked behind his car. The speed at which the image of the truck

appears to approach the driver will be:-

(i) 1m/s (ii) 3 m/s

(iii) 8 m/s (iv) 4 m/s​

Answer 1

Answer:

Correct option is (ii) 2m/s.

As the car moves 2m backward, the mirror also moves 2m backward, so the image comes 2m forward.
