Solution for On-Line Homework 6 Energy I Solution to On-Line Homework Problem 6.1() Problem: When does an interaction occur, according to physicists? (Choose the best answer.) Select One of the Following: (1) When two objects touch each other. (2) When two objects collide. (3-Answer) When two objects affect each other such that one or both are accelerated. (4) At a concert, when you smile at the person next to you. Solution An interaction occurs when two objects affect each other such that both are accelerated. It may just look like one is accelerated, according to your reference frame, or if one object has a much greater inertia than the other. But we know if the system is isolated, both will experience equal and opposite changes in momentum, so both will accelerate. Total Points for Problem: 2 Points 1

Unformatted text preview: What kind of collision dissipates energy? Select One of the Following: (1) An elastic collision, although it conserves mo-mentum. (2) An elastic collision, and it also does not conserve momentum. (3-Answer) An inelastic collision, although it con-serves momentum. (4) An inelastic collision, and it also does not con-serve momentum. (5) An explosive collision, which we haven’t read about yet, so of course there is a question on it (maybe not. ..). Solution Any inelastic collision dissipates energy. The total ±nal ki-netic energy will be less than the total initial kinetic energy. The lost energy can go into heating, sound, deformation, etc. In a totally inelastic collision, the energy dissipated is the maximum amount allowed by conservation of linear momentum.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
