Question 1
A cylindrical drum with a radius of 0.5 m and mass of 10 kg is rolled down a slope. What is its moment of inertia?
💡 Hint: Use the moment of inertia formula for a solid cylinder.
Question 2
Two objects collide and stick together, producing an angular motion. Object A has a moment of inertia of 5 kg⋅m², and object B has 3 kg⋅m². Find the combined moment of inertia after the collision.
💡 Hint: You can directly add moments of inertia for the combined system.
