Question

The mirror is moving with a velocity 2m/s at angle 30° and the object is moving with a velocity 5m/s at angle 37° find the velocity of the image​

Answer 1

Answer:

ANSWER

The correct option is C

Given,

velocity=v

angle=θ

The image will move towards the plane mirror with - v velocity . The  - sign indicates that the image moves in opposite direction of the object. 

Well, if you ask the velocity of object relative to the object then it would be - 2v. It means that the object would experience that the image is moving towards it with velocity 2v. 

Since the object is moving horizontal direction so the component of the velocity is 2vcosθ
