LO11.5Your family started a new manufacturing business making outdoor benches for use in parks and outdoor venues two years ago. The business has been very successful, and sales are soaring. Because of this success, your family realizes that the equipment purchased to start the business will not last as long as expected because the company has needed to run twenty-four-hour production shifts for most of the past year. There has been a lot of wear and tear on the equipment. The original useful lives and salvage values are not as accurate as your family had hoped. Your aunt, who is the production manager for the family business, has approached you because she is concerned about this issue, and she knows you have had an accounting class. What advice do you have for her? How should the company readjust given the realities of the last few years?

Critical Thinking Two boxes of the same mass are pressed against pistons that compress and release the boxes on frictionless surfaces. Box A’s piston has a constant force F over a distance _x_ before the box is released while box B starts at zero force and increases linearly to a force of 2 _F_ before releasing the box at a distance of 1/2 _d_ . (a) Which of these boxes has the greatest speed after releasing from the piston? (b) Based on experimental data for trials similar to box A, an equation that fits the data is suggested for the change in kinetic energy, \Delta KE , which may not be correct: \Delta KE = KF^{1/2}x^{1/2} , where _K_ is a constant with appropriate units, _F_ is the applied force, and _x_ is the distance the piston moves in contact with the box. Is this equation consistent with your answer from part a? Explain why or why not. Does this equation make sense? Explain why or why not. (c) If the applied force of the piston is proportional to the distance in contact with the box, graph the work done on the box vs. the distance in contact with the piston and box.

(a) A novelty clock has a 0.0100-kg-mass object bouncing on a spring that has a force constant of 1.25 N/m. What is the maximum velocity of the object if the object bounces 3.00 cm above and below its equilibrium position? (b) How many joules of kinetic energy does the object have at its maximum velocity?

A monatomic ideal gas undergoes a quasi-static process that is described by the function p(V) = p_{1} + 3(V - V_{1}) , where the starting state is \left( {p_{1},V_{1}} \right) and the final state \left( {p_{2},V_{2}} \right) . Assume the system consists of n moles of the gas in a container that can exchange heat with the environment and whose volume can change freely. (a) Evaluate the work done by the gas during the change in the state. (b) Find the change in internal energy of the gas. (c) Find the heat input to the gas during the change. (d) What are initial and final temperatures?
