Moving Plane Mirror, Stationary Object

Q. A plane mirror is approaching you at a speed of 10 cm/sec You can see your image in it. At what speed will your image approach you

1. 10 cm/sec
2. 5 cm/sec
3. 20 cm/sec
4. 15 cm/sec

Q. The object and image velocities are always equal in magnitude but in opposite direction.

1. True
2. False

Q. For plane mirror components of velocities of object and image are equal and opposite in nature with respect to mirror.

1. True
2. False

Q. A man is approaching a plane mirror with constant acceleration of 4 $m/s^2$. Initially the person is at rest. Mirror is moving towards the person with a constant velocity of 4 m/s. The correct variation of velocity of image of man (wrt ground) vs time is best given by consider leftwards as positive)

Q. Calculate the velocity of the image with respect to a stationary observer in the following situation (Object moving at an angle with mirror and mirror moving at an angle with object).

1. $5\sqrt{11}m/s$
2. $5\sqrt{5}m/s$
3. $5\sqrt{26}m/s$
4. $5\sqrt{33}m/s$

Q.
My cute puppy, Jenny, saw a mirror for the 1st time in its life. Thinking, of course, that it was another dog she was seeing, she started barking and running towards the mirror with a speed of 10 cm/s. Now, I started moving the mirror towards Jenny with a speed of 5 cm/s, just to mess with her. How fast will Jenny see 'the other dog' (her image) running? (The mirror is a plane mirror. Also, assume Jenny to be a point object, she's tiny, and far from the mirror, so not a bad assumption!)

1. $30\frac{cm}{s}$, away from her.
2. $30\frac{cm}{s}$, towards her.
3. $20\frac{cm}{s}$, towards her
4. $20\frac{cm}{s}$, away from her.

Q. A point object is kept near a plane mirror. The mirror starts moving away from the object with a speed of $4cm/s$. The velocity of the image is

1. $8cm/s,towardstheobject$
2. $8cm/s,awayfromtheobject$
3. $4cm/s,towardstheobject$
4. $4cm/s,awayfromtheobject$

Q. For plane mirror components of velocities of object and image are equal and opposite in nature with respect to mirror.

1. True
2. False
