The image of a stationary person is formed by a plane mirror moving at 60° to its normal. The speed of the image as seen by the person himself is:

Answer:

Solution:

Velocity of the mirror parallel to the mirror does not change the image velocity.

Mirror speed perpendicular to the mirror $= v cos 6 0^{\circ} = \frac{v}{2}$ .

Speed of image $= 2 \times \frac{v}{2} = v$ .

Equal to the speed of the mirror.
