A hoop of radius 0.50 m and a mass of 0.020 kg is released from rest and allowed to roll down to the bottom of an inclined plane.
A hoop of radius 0.50 m and a mass of 0.020 kg is released from rest and allowed to roll down to the bottom of an inclined plane. The hoop rolls down the incline dropping a vertical distance of 3.0 m. Assume that the hoop rolls without slipping. (a) Determine the total kinetic energy at the bottom of the incline. (b) How fast is the hoop moving at the bottom of the incline?
