7.15. Model: The hanging block and the rail car are objects in the systems. Visualize: Solve: The mass of the rope is very small in comparison to the 2000-kg block, so we will assume a massless rope. In that case, the forces 1 T G and 1 T G act as if they are an action/reaction pair. The hanging block is in static equilibrium, with net 0 N, F = G so 1 block 19,600 N.

    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.
