The writing on the passenger-side mirror of your car says
"Warning! Objects in mirror are closer than they appear" (Figure
1). There is no such warning on the driver's mirror. Consider a
typical convex passenger-side mirror with a focal length of -80 cm.
A 1.8-m-tall cyclist on a bicycle is 22 m from the mirror. You are
1.0 m from the mirror, and suppose, for simplicity, that the
mirror, you, and the cyclist all lie along a line
Part A
How far are you from the image of the cyclist?
Part B
How far would you have been from the image if the mirror were
flat?
Part C
What is the image height?
Part D
What would the image height have been if the mirror were
flat?
Express your answer with the appropriate units.
