Question 1
A rod of length L pivots about one end. If the mass of the rod is M, find its moment of inertia and angular momentum when it rotates with angular velocity \(\omega\).
💡 Hint: Use the formula for moment of inertia for a rod.
Question 2
Consider a rotating disk with radius R and mass M rolling without slipping. If it rotates with angular velocity \(\omega\), calculate its angular momentum.
💡 Hint: Recall the relationship between rolling and angular velocity.
