Challenge Problems
Push your limits with challenges.
Question 1
A disk starts from rest and accelerates to a speed of 10 rad/s in 4 seconds. Find the angular acceleration and the total angle rotated during this time.
💡 Hint: Use both the angular acceleration and displacement formulas.
Question 2
A flywheel is rotating with an initial angular velocity of 8 rad/s. It experiences a constant angular acceleration of 0.5 rad/s². Determine its angular velocity after 10 seconds and the total angle turned.
💡 Hint: Apply the angular velocity and displacement equations accordingly.
