1. A solid cylinder has a radius of 8 cm and a mass of 2 kg. Meanwhile, a solid ball has a radius of 5 cm and a mass of 4 kg. If the two objects rotate with an axis through their center, determine the ratio of the moment of inertia of the cylinder and the ball.
Solid cylinder radius (r) = 8 cm = 0.08 m
Solid cylinder mass (m) = 2 kg
Solid ball radius (r) = 5 cm = 0.05 m
The mass of the solid ball (m) = 4 kg
Wanted: Comparison of the moment of inertia of a cylinder and a ball
