3/77. Small object is on a conical dish. The coefficient of static friction between the object and the dish is 0.30. For what ω range will the object stay on the dish without slipping (assume angular acceleration may be neglected)? What is your first step?

    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.

    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.
