Question 26

A small toy drone is flying vertically downwards towards a flat, horizontal mirror on the floor. At a particular instant, the drone is at a height of 2.5 m above the mirror and is descending at a speed of 3.0 m/s.

What is the distance between the drone and its virtual image, and what is the speed of the image relative to the mirror?

A

Distance =2.5 m= 2.5\text{ m}=2.5 m; Speed =3.0 m/s= 3.0\text{ m/s}=3.0 m/s

B

Distance =2.5 m= 2.5\text{ m}=2.5 m; Speed =6.0 m/s= 6.0\text{ m/s}=6.0 m/s

C

Distance =5.0 m= 5.0\text{ m}=5.0 m; Speed =3.0 m/s= 3.0\text{ m/s}=3.0 m/s

D

Distance =5.0 m= 5.0\text{ m}=5.0 m; Speed =6.0 m/s= 6.0\text{ m/s}=6.0 m/s
