Answer 2

The correct answer is 7 m/sec towards left.

Given: Velocity of object = 3 m/sec.

Velocity of mirror = 2 m/sec.

To Find: Velocity of image.

Solution:

Take Right side as positive and left side as negative.

Velocity of object = ($V_{o}$)= +3 m/sec.

Velocity of mirror = ($V_{m}$) =-2 m/sec.

Velocity of object with respect to mirror $V_{om}$.

$V_{om} =V_{o} -V_{m}$

$V_{om} =3-(-2)$

$V_{om} =5$ m/sec.

Velocity of image with respect to mirror.

$V_{im} =V_{i} -V_{m}$

$V_{i} =V_{im} +V_{m}$

If velocity of object with respect to mirror is +5 m/sec then the velocity of image with respect to mirror should be its opposite that is -5 m/sec.

$V_{i} =-5+(-2)$

$V_{i} =-7$ m/sec

Hence, velocity of image is 7 m/sec towards left.
