1. A pottery wheel with moment of inertia I = 0.14 kg m2 is spinning at 5 radians/sec. How much kinetic energy does it have? 2. Ceres is the largest asteroid in the belt between Mars and Jupiter. It has an average radius of 475 km and a period of rotation of 9.07 hours. Calculate its angular momentum if the mass is 9.42 x 1020 kg The moment of inertia of a solid sphere I = 2/5 mR2
8. Th e moment of inertia for a wagon wheel can be calculated by taking the sum of the moment of inertia for a hoop (radius 1.2 m) rotating about a Cylinder axis (mass 3 kg) and three rods of length 1.2 m, rotating about their center perpendicular to their length, each of mass o.8 kg. If the wheel is rotating at an angular speed of 2.5 rad/s, what is the wagon wheel's kinetic energy as it spins in place?...
The pulley shown (Figure 1) has a moment of inertia IA = 0.625 kg⋅m2 , a radius r = 0.250 m , and a mass of 20.0 kg. A cylinder is attached to a cord that is wrapped around the pulley. Neglecting bearing friction and the cord’s mass, express the pulley’s final angular velocity in terms of the magnitude of the cord’s tension, T (measured in N), 4.00 s after the system is released from rest. Use the principle of...
