Constants You are testing a small flywheel (radius 0.166 m) that will be used to store a smal amount of energy. The flywheel is pivoted with low-triction bearings about a horizontal shaft through the flywheelCs center. A thin, light cord is wrapped multiple times around the rim of the flywheel. Your lab has a device that can apply a specified horizontal force F to the free end of the cord. The device records both the magnitude of that force as a function of the horizontal distance the end of the cord has traveled and the time elapsed since the force was first applied. The flywheel is intially at rest. • Part A You start with a test run to determine the flywheelcs moment of inertia I. The magnitude F of the force is a constant 25.0 N, and the end of the rope moves 8.35 m in 2.00 s. What is 1? Express your answer with the appropriate units. ? 1- Value Units Submit Request Answer • Part B In a second test, the fiywheel again starts from rest but the free end of the rope travels 6.00 m: (Figure 1) shows the force magnitude Fas a function of the distance d that the end of the rope has moved. What is the kinetic energy of the tywheel when d= 6.00 m? Express your answer with the appropriate units. ?
