Challenge Problems
Push your limits with advanced challenges
A solid disk of mass 10 kg and radius 0.5 m rolls down a hill without slipping. Calculate its translational and rotational speeds at the bottom if it starts from rest from a height of 2 m. Assume no frictional losses.
💡 Hint: Think about the energy conservation principle.
A disk with a radius of 0.2 m is rotating at 15 rad/s. Calculate the linear velocity of a point on the edge of the disk.
💡 Hint: Relate linear velocity directly to angular velocity along the edge.
