You need to find the moment of inertia of a large wheel about an axis through its center. The radius of the wheel and its mass are 0.320 m and 30.0 kg, respectively. You design an experiment in which you mount the wheel, using frictionless bearings, on a horizontal axis through the wheel's center. Then, you wrap a light string around the wheel and hang a 7.00-kg block from the free end of the rope. When you release the mass from rest from 2.50 m above the ground, the wheel turns as the rope unwinds and the block has a speed 5.60 m/s just before it hits the ground.
A) Use energy considerations to find the rotational kinetic energy of the wheel at the moment the block is about to hit the ground.
B) What is the mo of inertia of the wheel you found from this experiment?
C) Is it possible to build a wheel that has a moment of inertia 10 kg. m2 with the mass and the radius given above? Explain.
