Challenge Problems
Push your limits with advanced challenges
A spherical object rolls without slipping down an inclined plane. Describe the relationship between its linear speed at the base of the incline and its angular speed.
💡 Hint: Analyze the moment of inertia and how rolling affects speed.
A rigid body is subjected to a net external torque resulting in an angular acceleration of α. If its moment of inertia is I, derive an expression for the angular momentum of the body.
💡 Hint: Connect torque to angular momentum with τ = dL/dt.
