Work sheet 2– Chp 11 – Conservation of Angular Momentum 1. A 60.0-kg woman stands at the western rim of a horizontal turntable having a moment of inertia of 500 kg · m 2 and a radius of 2.00 m. The turntable is initially at rest and is free to rotate about a frictionless, vertical axle through its center. The woman then starts walking around the rim clockwise (as viewed from above the system) at a constant speed of 1.50 m/s relative to the Earth. Consider the woman–turntable system as motion begins. (a) In what direction and with what angular speed does the turntable rotate? (b) How much chemical energy does the woman's body convert into mechanical energy of the woman– turntable system as the woman sets herself and the turntable into motion? 2. A wad of sticky clay of mass m and velocity i is fired at a solid cylinder of mass M and radius R (see figure). The cylinder is initially at rest and is mounted on a fixed horizontal axle that runs through its center of mass. The line of motion of the projectile is perpendicular to the axle and at a

    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.
