If an observer is moving away from a stationary plane mirror at a speed of $6 \, m/s$,then the speed of the image with respect to the observer is ..... $m/s$.

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

$A$ plane mirror is placed along the $x$-axis facing the negative $y$-axis. The mirror is fixed. $A$ point object is moving with a velocity of $3\hat{i} + 4\hat{j}$ in front of the plane mirror. Find the relative velocity of the image with respect to the object.

The speed at which the image of a luminous point object is moving,if the luminous point object is moving at speed $v_0$ towards a spherical mirror along its axis,is (Given: $r =$ radius of curvature,$u =$ object distance):

Find the velocity of the image in the situation shown in the figure. (All velocities are in $m/s$)

An object approaches a convex mirror of radius of curvature $20 \,m$ along its optical axis. The image is observed to move from $\frac{25}{3} \,m$ to $\frac{50}{7} \,m$ from the mirror in $30 \,s$. What is the speed of the object in $km/h$?
