# Work-energy theorem the work-energy theorem states kf = ki + wall, where wall is the work done by all forces that act on the object, and ki and kf are the initial and final kinetic energies, respectively. the work-energy theorem states that a force acting on a particle as it moves over a changes the energy of the particle if the force has a component parallel to the motion. choose the best answer to fill in the blanks above: distance / potential distance / kinetic vertical displacement / potential none of the above to calculate the change in energy, you must know the force as a function of the work done by the force causes the energy change. choose the best answer to fill in the blank above: acceleration work distance potential energy to illustrate the work-energy concept, consider the case of a stone falling from xi to xf under the influence of gravity. using the work-energy concept, we say that work is done by the gravitational ,resulting in an increase of the energy of the stone. choose the best answer to fill in the blanks above: force / kinetic potential energy / potential force / potential potential energy / kinetic rather than ascribing the increased kinetic energy of the stone to the work of gravity, we now (when using potential energy rather than work-energy) say that the increased kinetic energy comes from the of the energy. choose the best answer to fill in the blanks above: work / potential force / kinetic this process happens in such a way that total mechanical energy, equal to the of the kinetic and potential energies, is . choose the best answer to fill in the blanks above: sum / conserved sum / zero sum / not conserved difference / conserved

Afood processing facility makes sweetened iced tea by feeding 1.00 kg h2o/min of water along with m1 kg of dry tea leaves/min into a brewer. from there, the leaves and water enter a filter that separates m2 kg of wet tea leaves/min from unsweetened tea. a 0.85 mass fraction of water leaves in the wet tea leaf stream along with 90.0% of the original mass of tea leaves. the unsweetened tea proceeds to a mixer where sugar is added. the sweetened tea enters a final filter where m4 kg of ice is added, and any undisolved sugar is removed in a slurry that is 75.0% by mass sugar, 25.0% water. this slurry is recycled back to the mixer along with m3 kg of fresh sugar/min. the sweetened iced tea leaving the final filter is 10.0% by mass sugar, 89.0% by mass water (all of the added ice has melted), and 1.0% by mass extracts from the tea leaves. a flow rate of m5 kg of sweetened iced tea/min is desired. if m5 is 1.65 kg/min, what are the flow rates of dry tea leaves, fresh sugar, and ice required?
