Unformatted text preview: 9. A 10 kg block is set in motion up a 20 degree inclined plane with an initial speed of 8.0 m/s. With no additional forces applied, the block comes to rest after traveling some distance up the plane. a. Calculate the change in kinetic energy of the block. b. Calculate the change in gravitational potential energy of the block. 0. Assuming the interface between the block and the plane is fiictionless, calculate the distance up the surface of the plane the block will travel. d.

    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.
