Wrecking balls of different masses were swung against a wall. Experimenters measured the distance the wall moved after each swing and recorded the data in the table below. Look at the data provided in the following table and choose the statement that explains the relationship about mass and kinetic energy.

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
