Physics 2210 -Fall 201 6 EXAM 2 D Name: Z-LcX/ Discussion TA: Unid: Discussion Section: r. Ant hony Pantziris 1 Show all Work!! Circle your answer(s). A rough inclined plane of angle 6 = 35.0° has a spring of spring constant k = 400 N/m fastened at the bottom, as shown in the picture. A block of mass m = 0.450 kg is placed on the incline at a distance d= 0.300 m from the uncompressed spring and it is given an initial speed v. The block collides with the spring and compresses it a distance of^c max = 0.160 m when it momentarily comes to rest. The coefficient of kinetic friction between the block and the inclined surface is (a) (b) (c) (a,) [4 pts.J Calculate the total work done by the gravitational force on the block. [4 pts.J Calculate the total work done by the frictional force on the block. [12 pts.J What is the initial speed v of the block? A/ ^ Cc) - VU

    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.
