A 10 kg solid disk of radius 0.5 m rotates about its center. Calculate the angular momentum when it rotates at 60 rad/s.
💡 Hint: Use the moment of inertia formula for disks, then apply it to find angular momentum.
A flywheel is accelerating at 2 rad/s². If its moment of inertia is 3 kg m². Calculate the torque being applied.
💡 Hint: Remember that torque correlates with moment of inertia and angular acceleration.
