The light on the ceiling is 3.375m above the ground. When a thin lens is placed 25cm above the ground, a minified image of the light from the ceiling is formed on the ground. What is the primary focal length of the thin lens? If the image of the light formed is 8cm x 2.5cm in size, how large is the actual light?

A 25kg block is placed 2.7m above the ground on a frictionless ramp. At the bottom of a ramp there is an ideal spring. A. If the block is let go, how fast will the block be moving at the bottom of the ramp? B. The block runs into the spring and compresses the spring a total of .35m before coming to a stop. What is the spring constant of the spring? The block then slides back up the ramp....

When an object is placed at the proper distance to the left of a converging lens, the image is focused on a screen 31.0 cmto the right of the lens. A diverging lens is now placed 14.2 cm to the right of the converging lens, and it is found that the screen must be moved 19.5 cm farther to the right to obtain a sharp image. What is the focal length of the diverging lens? ......... cm
