Question 1
A rolling cylinder has a radius of 0.5 m and moves with a linear velocity of 4 m/s. Calculate its angular velocity.
💡 Hint: Remember the relationship between linear and angular velocity.
Question 2
Two disks have different moments of inertia: one is 1 kg·m² and the other is 3 kg·m². If both rotate with the same angular velocity of 2 rad/s, compare their angular momenta.
💡 Hint: Remember that angular momentum depends directly on both moment of inertia and angular velocity.
