KIITEE Mock Test - 6 - Question 7

A man runs towards a mirror with a speed of 15 m-s-1. What is the speed of his image relative to the man is ?

Detailed Solution for KIITEE Mock Test - 6 - Question 7

Speed of man toward the mirror (V) = 15 m/s.

  • When the object moves with speed V towards (or away) from the plane mirror then image also moves towards (or away) with speed V.
  • But the relative speed of image w.r.t. the object is 2V.
  • Therefore, relative speed of image w.r.t. object is = 2 × 15 = 30 m/s.
