A person pushes a refrigerator across a horizontal floor. The mass of the refrigerator is 110 kg, the coefficient of static friction between the refrigerator and the floor is 0.85, and the coefficient of kinetic friction between the refrigerator and the floor is 0.59.
(a) If the refrigerator is initially at rest, determine the minimum magnitude of the force that the person must exert horizontally on the refrigerator to cause it to move.
N
(b) Once the refrigerator is moving, determine the magnitude of the force that the person must exert horizontally on the refrigerator to keep it moving at a constant speed.
N
(c) Determine the acceleration of the refrigerator if the person applies a horizontal force of magnitude 950 N on the refrigerator.

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?
