A large turntable with radius 6.00 m rotates about a fixedvertical axis, making one revolution in 8.00 s. The moment of inertia ofthe turntable about this axis is 1200 kg . m2. You stand, barefooted, atthe rim of the turntable and very slowly walk toward the center, along aradial line painted on the surface of the turntable. Your mass is 70.0 kg.Since the radius of the turntable is large, it is a good approximation totreat yourself as a point mass. Assume that you can maintain your balanceby adjusting the positions of your feet. You find that you can reacha point 3.00 m from the center of the turntable before your feet beginto slip. What is the coefficient of static friction between the bottoms ofyour feet and the surface of the turntable?
Johnny Manziel has decided that he’s a terrible quarterback (he’s pretty mad about it) andwants to become a kicker, but he’s concerned about the shoe he has chosen to kick withand how it will impact the inertia of his leg. The moment of inertia of the lower leg andfoot about an axis through the knee joint is 0.20 kg·m2. What is the moment of inertia ofthe leg and foot about the knee joint if a 0.50 kg shoe is worn on the foot? Assume thatthe shoe’s mass is all concentrated in one point 45 cm from the knee joint
In ice figure skating, a couple execute a“top” (see picture). The centre of mass ofthe woman (58 kg) is situated 1.3 m fromthe axis of rotation which is vertical andpasses through the centre of mass of theman (85 kg). They are spinning at aconstant angular velocity equal to ?? rad/sand the man and woman have moments ofinertia, about their own centres of mass, equal to 1.6 and 2.5 kg.m2 respectively. Then the woman grabs the neck of the man. At this point, her moment of inertia decreases to 1.4 kg.m2 and her body centre of gravity is 0.9 m from the axis of rotation. Determine the new angular velocity.Hints: This is a conservation of angular momentum problem, and needs the parallel axis theorem to determine moments of inertia about the axis of rotation. The skaters are moving as one body with one angular velocity, but they each have their own moments of inertia given relative to their own CoMs. For the man, that’s fine...the axis they’re rotating about passes through his CoM, but the…

Heis set rotating about the vertical axis, making one revolution in 2.0 s.Find his final angular velocity if he pulls the dumbbells inward to hisstomach. His moment of inertia (without the dumbbells) is 3.0 kg .m2with arms outstretched and 2.2 kg # m2 with his hands at his stomach.The dumbbells are 1.0 m from the axis initially and 0.20 m at the end.
