The side mirrors on cars are convex mirrors. If the side mirror on the driver side of your car has a focal length with a magnitude of 5.30 m and a truck is at a distance of 3.00 m from the mirror, determine the following.
(a) image distance of the truck (Include the appropriate positive or negative sign.)
----------m
(b) magnification for this object distance (Include the appropriate positive or negative sign.)
-----------
