Two thin lenses with a focal length of magnitude 17.0 cm, the first diverging and the second converging, are located 12.8 cm apart. An object 3.40 mm tall is placed 28.3 cm to the left of the first (diverging) lens. How far from this first lens is the final image formed?

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
