Question

If an object moves towards a plane mirror with a speed v at an angle theta to the perpendicular to the plane of the mirror, find the relative velocity between the object and the image

  1. v    
  2. 2v    
  3. 2 v cos invisible function application theta    
  4. 2 v sin invisible function application theta    

The correct answer is: 2 v cos invisible function application theta


    From figure it is clear that relative velocity between object and it's image = 2v cosq
