So its angular size at your eye is ′ = == θ h d 006 00239 . . m 2.51 m rad . (e) Your brain assumes that the car is 1.50 m high and calculate its distance as ′= d h 62 8 . . m 0.023 9 P36.20 (a) The image starts from a point whose height above the mirror vertex is given by 111 2 pq f R +== 1 300 11 0500 .. m m += q . Therefore, q = 0600 . m . As the ball falls, p decreases and q increases. Ball and image pass when qp = . When this is true, 1 2 1 pp p = m or p 1 100 = m . As the ball passes the focal point, the image switches from infinitely far above the mirror to infinitely far below the mirror. As the ball approaches the mirror from above, the virtual image approaches the mirror from below, reaching it together when
