Challenge Problems
Push your limits with challenges.
Question 1
A disk with a radius of 1 m rotates at 4 rad/s. What is the linear speed of a point on its edge? If the radius doubles, what is the new speed?
💡 Hint: How does changing the radius impact speed?
Question 2
If an object is spinning and its angular velocity triples while its radius remains unchanged, what happens to the linear velocity of points on that object?
💡 Hint: How do both quantities relate with each other?
