7A-C/D Win 09 Quiz 2 DL Sec Last 6 digits ID # Name (Last, First) Grade 1. A skier begins sliding down a hill from an initial stop at a height of 30 m. a) If we ignore any air resistance or friction from the snow, how fast would the skier be moving when she reaches a height of 20 m? Justify fully your answer. b) In a more realistic problem, we can't ignore friction. Suppose the skier has reached 10 m/s speed at a height of 20 m, and still is traveling 10 m/s at the bottom of the hill. Write down (and explain how you got it) an energy conservation equation describing the skier's path from 20 m to the bottom of the hill.

    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.
