Question

A man runs towards a mirror at a speed of 15 m/s. The speed of the image relative to the man is (A) 15 ms -1 (B) 30 ms -1 (C) 35 ms -1 (D) 20 ms -1

Relative velocity of image w.r.t. man =15-(-15)=30 m / s <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/7e2ab6f8a599e94516ca1ec7c8066383-.png" />

Q. A man runs towards a mirror at a speed of $15 m / s$ . The speed of the image relative to the man is

$15 m s^{- 1}$

$30 m s^{- 1}$

$35 m s^{- 1}$

$20 m s^{- 1}$

Relative velocity of image w.r.t. man
$= 15 - (- 15) = 30 m / s$

Q. A man runs towards a mirror at a speed of 15m/s. The speed of the image relative to the man is

15ms−1

30ms−1

35ms−1

20ms−1
