Academics

A wagon wheel 56 cm in diameter is mounted on a central axle where it spins at 180 revolutions/min. The wheel can be thought of as a circular hoop of mass 2 kg, and each of the 12 500 g spokes can be thought of as thin rods rotating about their ends.

What is the moment of inertia of the entire wheel? kg·m²

What is the wheel's rotational kinetic energy? J
