A water droplet is descending towards a horizontal plane mirror. At one instant, the droplet is $1.5\,\text{m}$ above the mirror and moving at a speed of $2.0\,\text{m/s}$. What is the separation between the droplet and its image, and what is the speed of the image at this instant?
- Adistance: $1.5\,\text{m}$; speed: $2.0\,\text{m/s}$
- Bdistance: $1.5\,\text{m}$; speed: $4.0\,\text{m/s}$
- Cdistance: $3.0\,\text{m}$; speed: $2.0\,\text{m/s}$
- Ddistance: $3.0\,\text{m}$; speed: $4.0\,\text{m/s}$
