**Educational Text Transcription:**

You unconsciously estimate the distance to an object from the angle it subtends in your field of view. This angle θ in radians is related to the linear height of the object \( h \) and to the distance \( d \) by \( θ = h/d \). Assume that you are driving a car and that another car, 1.50 m high, is 22.0 m behind you.

**Image Descriptions:**

1. **Photo Description:**
   - A photo of a passenger-side rearview mirror displaying the typical warning: "Objects in mirror are closer than they appear." In the reflection, a large truck is seen behind the car.

2. **Cartoon Illustration:**
   - A cartoon depicts a woman looking into the rearview mirror while driving, with the mirror showing a close-up of a car behind and the same warning text.

**Questions:**

(a) Suppose your car has a flat passenger-side rearview mirror, 1.55 m from your eyes. How far from your eyes is the image of the car following you?
- **Answer:**
  \[\_\_\_\_\] m

(b) What angle does the image subtend in your field of view?
- **Answer:**
  \[\_\_\_\_\] rad

(c) Suppose instead your car has a convex rearview mirror (see figures) with a radius of curvature of magnitude 1.70 m. How far from your eyes is the image of the car following you?
- **Answer:**
  \[\_\_\_\_\] m

(d) What angle does the image subtend at your eyes?
- **Answer:**
  \[\_\_\_\_\] rad

(e) Based on its angular size, how far away does the following car appear to be?
- **Answer:**
  \[\_\_\_\_\] m
