The moment of inertia of a meter stick of length L = 100 cm and mass m = 50 g about a perpendicular axis through its center is mL2/12. Two 34 g masses are attached to the stick, at 29 cm to either side of the center. What is the moment of inertia of the system in units of kg cm2 about the perpendicular axis through the center of the stick? Enter an integer. Some special vehicles have spinning disks (flywheels) to store energy while they roll downhill. They use that stored energy to lift themselves uphill later on. Their flywheels have relatively small moments of inertia but spin at enormous angular speeds. How would a flywheels kinetic energy change if the moment of inertia was 5 times larger but the angular speed was 5 times smaller?

O It depends on the mass of the flywheel. O It will increase by a factor of 5. O It will decrease by a factor of 2. It will decrease by a factor of 5.A hoop (I = mrz) and a disk (I = (1/2)mr2) with the same mass and the same radius roll down an incline of height h and angle theta. If they both start from rest at t = 0, which one will reach the bottom rst? 0 They both will arrive at the same time. (I) The disk. 0 The hoop
