A motor car is fitted with a convex driving mirror of focal length 20 cm. A second motor car 2 m board and 1.6 m high is 6 m away from the first car.
Calculate the position and size of the image of the second car seen in the mirror of first.

A motor car is fitted with a convex driving mirror of focal length 20 cm. A second motor car 2 m board and 1.6 m high is 6 m away from the first car. If the second car is overtaking at a relative speed of 14ms^-1 , how fast will the image be moving and in what direction?
