Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A disk of radius 0.5 m and mass 10 kg spins at a rate of 4 rad/s. Calculate its angular momentum. What happens if its radius is doubled?

💡 Hint: Remember to use the moment of inertia formula for a disk.

Challenge 2 Hard

A spinning wheel has a moment of inertia of 3 kg m² and is experiencing a constant torque of 1.5 N·m. Calculate its angular acceleration. How long will it take to reach an angular velocity of 6 rad/s?

💡 Hint: Apply the definition of angular acceleration and the relationship between torque and angular momentum.
