There is a mirror in my car that has a warning stating that "objects in mirror are closer then they appear". If a 1.6 m tall vehicle located 4 m in front of that mirror produces an image that is 8 cm tall, what kind mirror is this? Find the radius of curvature of this mirror. Supplement your solution with a diagram. Specify the type of image, magnification, and image distance.
