A toy car is placed in front of a concave lens (focal length 94.6 cm) at the origin, with the x-axis running through the optical center of the lens. The car is wound up and released at (1 m, 0), and it moves at constant velocity -71.7i cm/s toward the lens. Find , the speed at which the image is moving, in cm/s, when the car is at (35.5 cm,0). The sign of your answer give the direction the image is moving along the x-axis

You unconsciously estimate the distance to an object from the angle it subtends in your field of view. This angle e in radians is related to the linear height of the object h and to the distance d by 8= h/d. Assume that you are driving a car and that another car, 1.50 m high, is 29.0 m behind you.

a box is somewhere at the left, on the central axis of the thin converging lens. The image Im of the box produced by the plane mirror is 4.00 cm “inside” the mirror. The lens–mirror separation is 10.0 cm, and the focal length of the lens is 2.00 cm. (a) What is the distance between the box and the lens? Light reflected by the mirror travels back through the lens, which produces a final image of the box. (b) What is the distance between the lens and that final image?
