Question

A plane mirror is approaching you 10m/s at what speed will the image approach you

Answer 1

Answer:If x is the distance between the object and the mirror, 2x is the distance between the object and its image because for a plane mirror object distance is equal to the image distance. So if the plane mirror is approaching the object with a speed of x/t, then the image will approach the object with a speed of 2x/t. So if x/t = 10 cm/s, 2x/t = 20 cm/s. Hence the image will approach you with a speed of 20 cm/s.

Answer 2

Answer:

So if the plane mirror is approaching the object with a speed of x/t, then the image will approach the object with a speed of 2x/t. So if x/t = 10 cm/s, 2x/t = 20 cm/s. Hence the image will approach you with a speed of 20 cm/s

Explanation:

V1/V2 = x/t /2x/t 10/V2 = 1/2 V2 = 10×2 V2 = 20 cm/s
