A block is dragged over a horizontal surface by an 80 N force acting 25° above the horizontal. The block is displaced 6.0 meters, and the coefficient of kinetic friction is 0.140. Find the work done on the block by the 80 N force, the normal force and gravitational force each respectively. What is the increase in internal energy of the block-surface system due to friction? Find the total change in the block's kinetic energy. Ja

Problem 96. Indicate the single lens type (converging or diverging) and object position that will lead to the following kind of images. If no single lens system can produce the particular image indicate that this is so. A) real, upright, enlarged image. B) huge image at "infinity". C) real, enlarged, inverted image. D) tiny inverted image very near the focal point. E) real, reduced in size, inverted image. F) virtual, reduced in size, upright image. G) virtual, enlarged, upright image. H) real, inverted image that is the same size as the object. I) virtual, enlarged, inverted image. Problem 97. You are handed a converging lens and you have a ruler. Describe two different simple ways to determine the focal length of this lens. Each way should involve making only one measurement.
