Atoy car is placed 29.0cm from a convex mirror. the image of the car is upright and one-sixth as large as the actual car. calculate the mirror's power in diopters.

The power of the mirror is -17.24 diopter.

Explanation:

Magnification of an image,m =

Distance of the object from the mirror = u = 29.0 cm

Distance of an image from the mirror = v

Magnification =

Focal length of mirror = -5.8 cm =-0.058 m

Power of the lens = P

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
