Find the location and height of the image produced by lense

Question

When two lenses are used in combination, the first one forms an image that then serves as the object for the second lens. The magnification of the combination is the ratio of the height of the final image to the height of the object. A 1.20cm -tall object is 50.0cm to the left of a lens of focal length of magnitude 40.0cm . A second lens, this one having a focal length of magnitude 60.0cm , is located 300cm to the right of the first lens along the same optic axis.

Part CFind the location and height of the image (call it I2) formed by the lens with a focal length of 40.0cm if the first lens is diverging and the second lens is a converging.

s?1, |y?1| =

______ cm

Part DI2 is now the object for the second lens. Find the location and height of the image produced by the second lens.

s?2, |y?2| =

______ cm
