Challenge Problems
Push your limits with challenges.
Question 1
A flywheel spins at an angular velocity of 10 rad/s. If a force is applied at its edge increasing the angular velocity to 15 rad/s, calculate the torque applied, given the moment of inertia is 2 kg·m².
💡 Hint: Use the relation Torque = I * α to connect all concepts.
Question 2
A rod pivoted at one end swings down from a horizontal position. Calculate the angular momentum at the vertical position if the mass is 3 kg and the length is 1.5 m.
💡 Hint: Think of how to relate linear motion to angular momentum.
