Question

A boy is running a way from a plane mirror with a speed of 10ms -1 . what is his relative speed with respect to his image? ​

Answer 1

Answer:

20m/s

Explanation:

when the boy run away from the plane mirror, his image will also move with the same speed, but in opposite direction. so, to find the relative velocity of two motions in opposite direction, we must add them. therefore, the answer will be 10+10 =20m/s
