Convex Mirror Physics

Question

A spherical convex mirror is placed at the end of a driveway on a corner with a limited view of oncoming traffic. The mirror has a radius of curvature of 1.85 m.

Where will the image of a car that is 12.4 m from the mirror appear?

Answer 1

The focal length is negative since it is convex and will be half the radius = 0.925

Using 1/di + 1/do = 1/f

1/di = -1/.925 -1/12.4

d- = -0.86 meters which is virtual upright and behind the mirror
